Keeping Up Appearances is a British sitcom created and written by Roy Clarke. It originally aired on BBC1 from 1990 to 1995. The central character is an eccentric and snobbish middle-class social climber, Hyacinth Bucket (Patricia Routledge), who insists that her surname is pronounced "Bouquet". The show consisted of five series and 44 episodes, four of which were Christmas specials. Production ended in 1995 after Routledge decided to move on to other projects. All 44 episodes have since been released on video, DVD and streaming media.

The sitcom follows Hyacinth in her attempts to prove her social superiority, and to gain standing with those she considers upper class. Her attempts are constantly hampered by her lower class extended family, whom she is desperate to hide. Much of the humour comes from the conflict between Hyacinth's vision of herself and the reality of her underclass background. In each episode, she lands in a farcical situation as she battles to protect her social credibility.

Keeping Up Appearances was an immense success in the UK, and also captured large audiences in the United States, Canada, Australia, Denmark, Finland, Sweden, Norway, Ireland, Belgium, and the Netherlands. By February 2016, it had been sold nearly a thousand times to overseas broadcasters, making it BBC Worldwide's most exported television programme ever. In a 2004 BBC poll it placed 12th in Britain's Best Sitcom. In a 2001 Channel 4 poll, Hyacinth was ranked 52nd on their list of the 100 Greatest TV Characters. The show has been syndicated on Gold and Drama in the UK, on PBS member stations in the United States and on 7TWO and 9Gem in Australia.
