The following is the collection of music videos that reached the number-one spot on the daily music video countdown show Total Request Live which aired on MTV from 1998 to 2008. Usually, the same video would stay at the number-one spot for a significant period of time until it was retired or honorably discharged from the countdown and put into a "hall of fame". The countdown was usually determined in various ways such as voting online on MTV.com, the Billboard charts, ratings on the radio and downloads over the internet.
TRL chose the top ten most iconic videos and aired them as their final countdown.
