Big Brother 2 (UK)

Big Brother 2001, also known as Big Brother 2, was the second series of the British reality television series Big Brother. The show followed eleven contestants, known as housemates, who were isolated from the outside world for an extended period of time in a custom built House. Each week, one or more of the housemates were evicted by a public vote. The last remaining housemate won a cash prize of £70,000.

As with the previous series, Big Brother 2 lasted 64 days. It launched on Channel 4 on 25 May 2001 and ended on 27 July 2001. Davina McCall returned as presenter for her second consecutive year. Ten housemates entered on launch night, with one additional housemate being introduced in the third week. It also spawned Big Brother's first ancillary show entitled Big Brother's Little Brother, presented by Dermot O'Leary.

The winner of this series was TBA.

This season was preceded by series one and followed by series three.
