As of October 2020, Cocomelon – Nursery Rhymes has the most videos in the top 50 with eleven, YouTube has two and Jingle Toons have two. For instance " Despacito", " Baby Shark Dance", and " Gangnam Style" all appear on this list, but also appear in the list of most-liked YouTube videos.

Note that the dislike count does not indicate the true unpopularity of a video, which is better represented by dislike percentage, also provided in the table. Of the 50 videos in this list, 6 also appear in the list of most-viewed YouTube videos and 4 appear in the list of most-liked YouTube videos. The feature served as a replacement for the previous five-star rating system, which was found to be ineffective because of the rare selection of ratings from two to four stars. YouTube implemented a like and dislike button on video pages from 2010 as part of a major site redesign. The dislike count was taken directly from the page of the video itself. This list of most-disliked YouTube videos contains the top 50 videos with the most dislikes of all time, as derived from YouTube charts.
