The Eurovision Song Contest 1974 was the 19th edition of the annual Eurovision Song Contest. It was held in the seaside resort of Brighton on the south coast of England. The BBC agreed to stage the event after Luxembourg, having won in both 1972 and 1973, declined to host it for a second successive year on the grounds of expense.

The winner of the 1974 contest was Sweden with the song "Waterloo" which was performed by ABBA, who later went on to become one of the most popular global recording acts of all time. Sweden's win was its first in the competition, and also the first victory for a country from the Scandinavian Peninsula.

ABBA are a Swedish pop group formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. The group's name is an acronym of the first letters of their first names arranged in a chiastic pattern. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1983. They have achieved 48 hit singles.
