Sweet (originally The Sweet) is a British rock band that rose to prominence as one of the main glam rock acts in the 1970s, with the original line-up consisting of Brian Connolly, Steve Priest, Frank Torpey, and Mick Tucker. Torpey was later replaced by Mick Stewart and then by Andy Scott in August 1970.

During the early years of 1971 and 1972, Sweet's musical style followed a marked progression from the Archies-like bubblegum style of the first hit, "Funny Funny", to a Who-influenced heavy rock style supplemented by a striking use of high-pitched backing vocals. The band achieved notable success in the UK charts, with thirteen Top 20 hits during the 1970s alone, five reaching number 2 and one, "Block Buster!", reaching number 1.

Sweet membership has undergone a number of changes, and during different periods Scott, Connolly and Priest also each formed their own "Sweet", resulting in the separate bands Steve Priest's Sweet, Andy Scott's Sweet and BC Sweet.
