The Second Stanhope Ministry was the ninth ministry of the Government of the Australian Capital Territory, and was led by Labor Chief Minister Jon Stanhope and his deputies Ted Quinlan (2004–2006) and Katy Gallagher (2006–2008).
The retirement of veteran member Bill Wood at the election created a vacancy in the ministry, and backbencher John Hargreaves, who had polled exceptionally well at the election, was appointed to fill the position.
The first, albeit minor, changes in March 2005 saw Deputy Chief Minister Quinlan pick up several new portfolios.
A much greater change occurred in April 2006 when Quinlan's retirement from politics sparked a major reshuffle and the appointment of a new minister in Andrew Barr.
A final change occurred in April 2007, when Simon Corbell was stripped of his responsibilities for planning after publicly criticising Chief Minister Stanhope over his handling of the area, and Stanhope chose to reactivate an environment and climate change ministry.
