You cannot see the specific users who view your Instagram Reels. Instagram only shows the total number of views on a Reel, but it does not reveal the identities of everyone who has watched it. However, if someone has liked or commented on your Reel, you will be able to see their usernames and profile pictures. Users with a Business or Creator account can access Insights to see aggregated data such as total views, likes, comments, shares, and other engagement metrics on their Reels, but individual viewers remain anonymous unless they interact publicly with the content.
