7

7 (also known as Madness 7) is the third studio album by the English ska and pop band Madness. Released in October 1981, it peaked at No. 5 on the UK Albums Chart. All but one track was recorded at Compass Point Studios in Nassau, Bahamas in the summer of 1981, the exception being "Grey Day" which was recorded in London earlier in the year. Although in 2011 co-producer Alan Winstanley stated in the Guided Tour of Madness boxed-set that much of the album was re-recorded in London when they returned from Nassau. The album title was band member Chas Smash's idea based on the lucky number 7.

In a retrospective review for AllMusic, Stephen Thomas Erlewine described 7 as "a great leap forward" for Madness, noting that while "they're still clearly the same nutty band that tore it up with One Step Beyond", the album "finds the group expanding its horizons considerably, ratcheting up the melodious pop quotient in their songwriting, as well as the distinctly English character sketches."
