UK national selection for the Eurovision Song Contest

Eurovision: You Decide is the most recent name of a BBC television programme that was broadcast annually to select the United Kingdom's entry for the Eurovision Song Contest. The show had previously gone under several other names, including Festival of British Popular Songs (1957), Eurovision Song Contest British Final (1959–1960), The Great British Song Contest (1996–1999), Eurovision: Making Your Mind Up (2004–2007), Eurovision: Your Decision (2008), and Eurovision: Your Country Needs You (2009–2010), but was known, for most of its history, as A Song for Europe (1961–1995, 2000–2003).

The selection process, originally broadcast on BBC One, has varied between selecting both the performer and song, or just the song in some years, and has been hosted by a variety of presenters over the years. For most years the public has been able to vote for the winner, in the past with postcard voting, where the viewers sent postcards with their vote to the BBC, but more recently televoting and online. In 2009 and 2010, the singer was chosen by a public vote and the song internally selected.

The most recent name and format, Eurovision: You Decide, was adopted in 2016, as between 2011 and 2015 the UK representative had been internally selected by the BBC, resulting in the televised selection show being suspended. The 2016 edition of You Decide was broadcast on BBC Four, while the You Decide editions between 2017 and 2019 were aired on BBC Two. In September 2019, the You Decide format was dropped in favour of a return to the internal selection method, in which BBC Studios partners with a music company (BMG in 2020 and 2021, and TaP in 2022 and 2023) to select and produce its entry. The internal selection process continues to be used as of 2025.

The format of the show and the manner in which the winner is chosen has gone through many mutations. In its early days, there was a round of televised semi-finals, with the winner chosen by regional juries situated across the country. This format was used until 1960. During this era the show was known as the "Festival of British Popular Songs" (1957) and "Eurovision Song Contest British Finals" (1959 and 1960).

In 1961 the show became known by its more familiar title, "A Song For Europe", with regional juries once more deciding the winner. Typically, during that period, singers would be invited by the BBC to choose and perform a song that they liked from the shortlist available. Household names such as Petula Clark, Lita Roza, Anne Shelton, Frank Ifield, Ronnie Hilton and David Hughes were amongst the contenders for the UK competition, none of whom were able to secure the much cherished ticket to the Eurovision final. In the early 1960s, record companies became involved in the selection process for the first time and submitted songs by their artists. This produced hits for Craig Douglas, Karl Denver, Jackie Lee, Kenny Lynch, Vince Hill and Ricky Valance, but again, none of them were selected to go forward to the Eurovision Song Contest final itself.

From 1964 up until 1975, an artist would be chosen by the BBC, and that artist would sing all six songs (five in 1966 and 1967) in the selection, and the public (bar 1964 and 1971) would choose by postcard which song they would like to represent them in the contest. Regional juries selected the winner in 1964. A postal strike in 1971 prevented the ballot from taking place, so regional juries were once again constructed to pick the winner. In 1972, national power cuts meant that the broadcast of the show was blacked out in many areas, leading to a much lower postal vote. In its early days of this format, only "light entertainment" singers were used, such as Kenneth McKellar and Kathy Kirby. However, the poor showing of McKellar in Luxembourg (he placed 9th of 18 entries with scores from only 2 countries, including top marks from Ireland) prompted the BBC to use more mainstream pop stars, which led to a run of successful results for the UK. This idea was dropped due to the low number of postal votes cast in the contest of 1975, in which all six songs were performed by The Shadows, and after objections from songwriters who felt The Shadows, and the BBC's selections in general, were not the sort of artists they wanted to represent their music.

After 1964, the "Song For Europe" selection process was incorporated into other BBC light entertainment shows, in addition to the songs being broadcast on BBC Radio programmes. Typically, the performer would sing one song a week either on their own series or as a guest on another regular BBC TV show, more often than not, televised on Saturdays. This culminated with the performer singing all the songs one after another in a special edition of the given show. From 1968 to 1975, these performances were then immediately repeated before viewers were asked to cast their votes by mail. The following week, the winning song would be announced and performed once more, although there was a two-week wait in 1965.

In 1968, Cliff Richard performed the songs only in a special edition of Cilla Black's eponymous TV series (broadcast on Tuesdays), without having sung them weekly beforehand. The various shows chosen for the "Song For Europe" performances were The Kathy Kirby Show (1965 shown on Fridays), Kenneth McKellar's A Song For Everyone (1966 shown on Thursdays), The Rolf Harris Show (1967), Cilla (1968 and 1973), Lulu (1969 and 1975), It's Cliff Richard! (1970, 1971 and 1972) and Clunk, Click... As It Happens (1974) – when in a break with the format, Olivia Newton-John performed three songs a week for two weeks rather than one a week for six weeks. Originally, Cilla Black's 1974 nine-part BBC series was also scheduled to feature the 'Song for Europe' process, but Black was uncomfortable at promoting another female singer (Newton-John) each week throughout the series' run and in a rather last minute decision, the BBC arranged to move the process to another show, necessitating the contracted process.
