The 1991 Triple J Hottest 100 was the third yearly poll of the most popular songs, according to listeners of the Australian radio station Triple J. From 1989 to 1991, listeners could vote for songs released in any year. There was no poll in 1992, and from 1993 onwards, the poll was restricted to songs released the same year. Supplementary "Hottest 100 of all time" polls allowing songs from any year were held in 1998 and 2009.
