Watt is the fifth studio album by the English blues rock band Ten Years After, released in 1970.

It was recorded in September 1970 except for the last track, a cover of Chuck Berry's "Sweet Little Sixteen", which is a recording from the 1970 Isle of Wight Festival.

Allmusic gave Watt a moderately negative review, saying it "had many of the same ingredients as its predecessor, Cricklewood Green, but wasn't nearly as well thought out."

They praised the band for performing as energetically as ever, but contended that Alvin Lee's compositions for the album are uniformly uninspired.
