How to Unlike a Comment on LinkedIn (and Undo Any Reaction)
How to unlike a comment on LinkedIn in two taps, whether the other person gets notified, and how to clean up reactions you left months or years ago.
By Animesh Kudake, Co-founder, Apna Project
The short version
- To unlike a comment on LinkedIn, hover over the reaction you left and click it again on desktop, or tap and hold it on mobile. The reaction is removed immediately.
- The same gesture works on posts, and it works for every reaction type, not just Like. Clicking a different icon swaps the reaction rather than removing it.
- LinkedIn tells your network when you react to something. It does not send a second notification when you undo it, but the original alert cannot be recalled.
- To clear old reactions in bulk, use your own Activity section and filter to Reactions, then remove them one at a time. There is no bulk unlike button.
- An accidental like is a small problem. Removing it quickly is worth doing, but re-liking and unliking repeatedly is more visible than the original mistake.
Cleaning up reactions from months ago
This is the harder request, and LinkedIn does not make it pleasant.
Go to your own profile, scroll to Activity, click Show all activity, and switch the filter to Reactions. You get a reverse chronological list of everything you have reacted to. Open the item, remove the reaction, go back, repeat.
There is no bulk unlike. There is no date filter. LinkedIn's guidance on managing your own shared content puts the practical range at content up to two years old, so anything older than that is effectively out of reach anyway.
Two things worth knowing before you spend an evening on this:
- Reactions on deleted posts are already gone. You cannot clean up what no longer renders.
- The Reactions filter and the Comments filter are separate. Clearing one does nothing to the other. If you are also auditing what you wrote, finding your comments on LinkedIn walks the parallel path.
People usually arrive at this task before a job search or after a role change, and the honest advice is to be selective. Removing four reactions you would not want a hiring manager to see is a good hour. Removing four hundred to sanitise your account is not, because nobody is reading that far back and the pattern of what you engage with is not something you can meaningfully rewrite.
Unlike, ignore, or double down
A quick decision rule, because most of these are not worth thinking about.
Unlike immediately if you reacted to something political, to a competitor's announcement in a way that reads as endorsement, or to a post you had not read. Thirty seconds of thought, then move on.
Leave it if you simply reacted to something mildly unremarkable. Nobody is auditing your Likes. The reaction bar is the lowest signal object on the platform and treating it as a statement of record is a good way to lose an afternoon.
Turn it into a comment if the reason you flinched is that a reaction was too thin a response. That is the genuinely useful move. A reaction is a footprint. A comment is a contribution, and it is the one that actually earns you anything. We laid out the difference in can you react to comments on LinkedIn.
Why accidental likes happen so often
Because the reaction target is small, it is placed exactly where your thumb rests while scrolling, and on mobile the tap and hold gesture that opens the reaction picker is one hesitation away from a plain tap that fires a Like.
That design is not an accident. Reactions are cheap by intent, because cheap engagement keeps a feed alive. It is also why they carry almost no weight in what a post actually gets shown to people.
We build Commenti, which drafts and posts LinkedIn comments on a pacing schedule, and one of the earliest product decisions was that it does not touch the reaction bar. It could. Auto-liking is trivial to build and it is what half the tools in this space lead with. We left it out because a like from an unattended process is the purest form of noise: it costs the sender nothing, it tells the recipient nothing, and it makes the account look like a script to anyone who checks the Activity tab.
The honest framing, since it applies to us too: LinkedIn's User Agreement prohibits third-party automation, and Commenti operates in that gray zone openly. What we can say is that the product is built to reduce risk, with daily caps, pacing, skip filters, and an approve mode where nothing goes out unread. Reduce is the only verb available. Nobody in this category can promise you immunity, and anyone who does is selling.
The short version
Click the reaction you left, again. That is the unlike. It works the same on posts and comments, on desktop and mobile. The person may have already been notified and there is nothing to be done about that. For old reactions, use your own Activity section filtered to Reactions and accept that it is one at a time. And if the reaction felt like the wrong response rather than the wrong target, write the comment instead.
Frequently asked questions
How do I undo a like on a LinkedIn comment?
Hover over the reaction icon under the comment on desktop and click it again, or tap and hold it on mobile and release without choosing anything. LinkedIn treats a second click on the same reaction as a removal. The count drops by one straight away and your name leaves the reactor list.
Does someone get notified when I unlike their comment?
LinkedIn sends a notification when you react, and its help documentation confirms reactions are shared with your network. It does not send a matching notification when you remove one. The original alert is already delivered though, so an unlike hides the reaction going forward rather than erasing the fact you left it.
How do I remove a like I left years ago?
Go to your own profile, open the Activity section, click Show all activity, and switch the filter to Reactions. Scroll to the item and remove the reaction from there. LinkedIn renders roughly two years of activity and offers no bulk removal, so old cleanups are manual.
Why can I not unlike a LinkedIn post or comment?
Usually the post was deleted, the author restricted who can interact with it, or the app is showing you a cached view. Refresh first. If the underlying content is gone, the reaction goes with it and there is nothing left to undo.

You meant to scroll. Your thumb landed on the reaction bar instead, and now you have congratulated a stranger on something you have not read. Knowing how to unlike a comment on LinkedIn takes about four seconds, and the mild panic that sends people searching for it usually lasts longer than the fix.
The gesture is the same one that created the problem, which is why nobody guesses it. You do not look for a Remove button. You press the thing you already pressed.
The two second version
On desktop, move your cursor over the reaction you left under the comment and click it again. On mobile, tap and hold the reaction icon. LinkedIn's own help page on reacting to posts and comments describes exactly this: to undo a reaction, "move your cursor over the Like icon or the reaction you chose, and click or tap it again."
The reaction disappears, the count drops by one, and your name leaves the list of reactors.
Two details that trip people up:
Does the other person find out
Partly, and the honest answer is less comforting than people want.
LinkedIn's help documentation states that posts and comments you react to "will be shared with your network, and they'll be informed of the reaction you chose." That notification fires on the react. It does not fire again when you undo.
So an unlike is quiet, but it is not time travel. If the notification already reached them, removing the reaction hides it from the post going forward rather than deleting the fact that it happened. In practice this almost never matters, because the volume of LinkedIn notifications means an alert from ninety seconds ago is already three screens down. It matters exactly once: when you accidentally reacted to something you had a professional reason not to touch, and the person is watching. In that case the unlike is still worth doing, and worrying about it further is not.
What you should not do is react, unlike, react again while you decide. Each of those is a fresh event. The indecision is more visible than the original slip.
