The Apprentice (British TV series) series 6

The sixth series of British reality television series The Apprentice (UK) was broadcast in the UK on BBC One, from 6 October to 19 December 2010; due to the 2010 General Election, which Alan Sugar had political ties with following his appointment as a Lord within the House of Lords, the BBC postponed the series' broadcast until Autumn of that year to avoid a potential conflict of interest from the broadcaster.

The sixth series is last to offer a six-figure job as a prize, before this particular area of the programme's format was changed for subsequent series at the request of Sugar. It is also the first series to feature Karren Brady as Margaret Mountford's successor to the role of Sugar's aide in the programme, after her initial appearance in this role for the first series of Young Apprentice. Despite announcing the previous year she was leaving the programme, Mountford retained a role within The Apprentice by taking over Brady's role as an interviewer in the Interviews stage. Alongside the standard twelve episodes, two specials were aired alongside this series – "The Final Five" on 9 December; and "Why I Fired Them" on 16 December.

Sixteen candidates took part in the sixth series, with Stella English becoming the overall winner, though she later caused controversy for the programme following her win that led to significant changes to the format of The Apprentice in later series. Excluding the specials, the series averaged around 7.87 million viewers during its broadcast.
