Adam Christopher Hills (born 10 July 1970) is an Australian comedian, radio and television presenter. In Australia, he hosted the music quiz show Spicks and Specks from 2005 to 2011, and again in 2021 onwards, and the talk show Adam Hills Tonight from 2011 to 2013. In the United Kingdom, he has hosted the talk show The Last Leg since 2012. He has been nominated for an Edinburgh Comedy Award, the Gold Logie Award and numerous BAFTA TV Awards.

Born in Loftus, Sydney, he began performing as a stand-up comedian in 1989 at the age of 19 and, since 1997, has produced ten solo shows which have toured internationally. He has performed at the Edinburgh Festival Fringe, the Melbourne International Comedy Festival and the Montreal Just for Laughs festival, earning three consecutive Edinburgh Award nominations for his Edinburgh shows in 2001, 2002 and 2003.

In 2002, he scored a minor hit in Australia with his single "Working Class Anthem", in which he sang the lyrics of the Australian National Anthem to the tune of "Working Class Man", a song by Australian rocker Jimmy Barnes.

Hills first appearance in comedy scene was in 1989 at the Sydney Comedy Store. He did breakfast radio on SAFM in Adelaide, as well as stand-up gigs and, by the mid-1990s, he decided to focus on live comedy. His first solo show premiered in 1997 and was called "Stand Up and Deliver", taking its name from an Adam and the Ants song. He has travelled widely, performing at the Edinburgh Festival Fringe, the Melbourne International Comedy Festival and the Montreal Just For Laughs festival. He has been nominated for three consecutive Edinburgh Comedy Awards for his 2001, 2002 and 2003 solo shows at the Edinburgh Fringe.

The title of his 2001 show, "Go You Big Red Fire Engine", was coined during a 1999 performance in Melbourne. Hills asked an audience member to yell his name to the audience and for the audience to yell it back, but instead the man yelled "Go you big red fire engine!" The phrase quickly became an audience chant, and Hills promised he would make it the name of his next show because, he says, "it was such an uplifting and genuinely silly moment." "Go You Big Red Fire Engine" later became the name of a second stand-up show and a comedy album. It also appeared in a Detroit newspaper, on a Swedish website, and was yelled by Senator Natasha Stott Despoja in the Australian Parliament.

Hills' artificial right foot is commonly used as a source of humour in his shows and the comedian has been known to remove it and pass it around. However, he had been performing live comedy for over a decade before he made reference to his prosthesis on stage, and it was only after "Go You Big Red Fire Engine" was nominated for a Perrier Award in 2001 that he began incorporating it into his act. Hills says he felt he could too easily have become a novelty act and that he "didn't want to be known as the one-legged comedian ... I wanted to prove myself as a comic before talking about this".

At his festival shows, Hills regularly performs alongside Leanne Beer, an Auslan sign interpreter, a move sparked by a performance he did in Adelaide at a disability art conference. An interpreter had been provided at the show, and Hills found that it not only allowed the deaf audience members to enjoy his material but was also an entertaining and fascinating experience for the hearing audience members. "Now I have hearing people who will only book [for sign interpreted shows]", he says.

Some of his influences include Chris Addison, Greg Fleet, Rich Hall, Daniel Kitson, Ross Noble and David O'Doherty.
