Are You Being Served? is a British television sitcom that was broadcast from 1972 to 1985. It was created and written by David Croft and Jeremy Lloyd. Croft also served as executive producer and director. Michael Knowles and John Chapman also wrote certain episodes. Produced by the BBC, the series starred Mollie Sugden, Trevor Bannister, Frank Thornton, John Inman, Wendy Richard, Arthur Brough, Nicholas Smith, Larry Martyn, Harold Bennett, Arthur English, and Mike Berry.

Set in London, the show followed the misadventures and mishaps of the staff and their regular rotating series of customers at the retail ladies' and gentlemen's clothing departments in the flagship department store of a fictional chain called Grace Brothers.

The series was broadcast on the BBC for 10 series, totalling 69 episodes between 8 September 1972 and 1 April 1985, including five Christmas specials. The sitcom proved a ratings hit with UK audiences, and gained international recognition when broadcast across several English-speaking countries, including Canada, New Zealand, Australia, the Republic of Ireland, and the United States; the latter gaining it a loyal following when PBS television stations began airing reruns in the mid-1980s, along with other British sitcoms.

Are You Being Served? was one of several television series predominant at the time that were adapted for the cinema screen, and a feature film of the same title was released in 1977. A spin-off television series, Grace & Favour ran from 1992 to 1993 with the same main cast. In 2004, Are You Being Served? was ranked 20th in a television countdown of Britain's Best Sitcom. A one-off revival episode with a new cast was created in 2016. The sitcom – including its pilot and Christmas specials – the spin-off and the film have since been released on DVD.

Are You Being Served? depicted the lives of the staff of a fictional department store, Grace Brothers. Its main characters served in the clothing departments for men and women, alongside their senior staff, maintenance workers and the store's owner. The sitcom focused on the relationships among staff, their attempts to improve sales, and the effects of local events that impacted the store's running.

A key humorous aspect of the series was a parody of the British class system, which permeated the interactions among management, sales personnel and the maintenance staff. The episodes rarely featured locations outside the store, with most of the action taking place on the shop floor and the staff-only areas. Characters also rarely addressed each other by their first names, even after work, instead using their surnames in the manner of "Mr", "Miss", or "Mrs".

The sitcom featured humour based on sexual innuendo, misunderstanding, mistaken identity, farce, and occasional slapstick. In addition, there were sight gags generated by outrageous costumes which the characters were sometimes required to wear for store promotions, and gaudy store displays sometimes featuring malfunctioning robotic mannequins. The show is remembered for its prolific use of double entendres. Alongside the comedy, some episodes also conducted specialised dance routines which were choreographed either to be natural or sometimes comedic in effect.

The idea for the show came from Lloyd's brief period in the early 1950s working at Simpsons of Piccadilly, a clothing store which traded for over 60 years until its closure in 1999. The inspiration for the store has also been credited to the former Clements of Watford where the concept of the floor walker character Captain Peacock was devised.
