Britain's Best Sitcom was a poll conducted in 2004 by the BBC to identify the United Kingdom's best situation comedy. The winner by over 60,000 votes was Only Fools And Horses, not a surprise to the British voting public due to its considerable popularity.

Out of a list of 100 sitcoms, viewers were asked to vote for their favourite by phone, text message and on the web. The top ten went forward to a final round of voting.

Ten special programmes were made before the final round, each about one of the Top 10, the programmes consisting of a celebrity speaking on behalf of their chosen sitcom as well as interviews with the stars and people that made it. For example, Johnny Vaughan spoke on behalf of Porridge, while Armando Iannucci represented Yes Minister/Yes Prime Minister.
