Chas & Dave (often billed as Chas 'n' Dave) were an English pop rock duo, formed in London by Chas Hodges and Dave Peacock.

They were most notable as creators and performers of a musical style labelled rockney (a portmanteau of rock and cockney), which mixes "pub singalong, music-hall humour, boogie-woogie piano and pre-Beatles rock 'n' roll". For a time, Rockney was also the name of their record label, their major breakthrough being "Gertcha" in 1979, which peaked at No. 20 in the UK Singles Chart, and was the first of eight Top 40 hit singles the duo played on. They had their biggest success in the early 1980s with "Rabbit" and "Ain't No Pleasing You". They also had nine charting albums. In October 2013 they released That's What Happens, their first studio album in 18 years.
