Annette Louise Ellis (born 13 October 1946) is an Australian politician who was a Labor Party member of the Australian House of Representatives from the Australian Capital Territory, from March 1996 to July 2010, representing the Division of Namadgi 1996–98 and the Division of Canberra 1998–2010.
In the 1996 federal election she contested the newly created seat of Namadgi against the Liberal Member for Canberra, Brendan Smyth. Notionally, the seat was very safe for Labor; as originally drawn it had a notional Labor majority of 10.9 percent. However, due to the heavy swing nationwide against the Keating government, Ellis was only assured of victory when she received a large flow of Green preferences on the third count. Ellis become one of the few Labor candidates to defeat a Liberal during the landslide election that brought the Howard government to power. Namadgi was abolished after only one cycle, and most of its territory was merged back into Canberra. Ellis transferred to Canberra, and won it easily. She continued to hold it with little difficulty until her retirement prior to the 2010 federal election.
Ellis was born in Melbourne, Victoria, and was a public servant, electorate adviser and ministerial adviser before entering politics. She was a member of the Australian Capital Territory Legislative Assembly from 1992 to 1995.
