Andrew John Hansen (born 18 September 1974) is an Australian comedian, musician and author, best known for being a member of satirical team The Chaser.

With Chaser colleague Chris Taylor, Hansen starred in a scripted radio comedy series on triple j titled The Blow Parade, which was released on CD and the iTunes Store.

Soon-to-be fellow Chaser member Charles Firth was one of the other two students featured, with Craig Reucassel and Chas Licciardello also making occasional background appearances.

Hansen's performance in the first season of CNNNN earned him the Australian Comedy Award for Outstanding Television Newcomer.

On the 17 October 2007 episode of The War, Hansen performed the song which satirised the lives of several deceased celebrities, including Peter Brock, Stan Zemanek, Princess Diana, Donald Bradman, Steve Irwin, John Lennon, Jeff Buckley and Kerry Packer, expressing the view that people with flaws during life are often disproportionately hailed as "top blokes" after death.
