Robert "Bob" Henrit (born 2 May 1944, Broxbourne, Hertfordshire) is an English drummer who has been a member of several musical groups, including Buster Meikle & The Daybreakers, The Hunters, Unit 4 + 2, The Roulettes, Argent and The Kinks.
Bob Henrit was originally the drummer with Buster Meikle & The Day Breakers, together with Russ Ballard on guitar and Roy Ballard, Russ`s older brother, on piano. All usually appearing on stage dressed in matching red jackets & was it black collars? Russ left stage, his brother Roy behind him, Bob stage right & Buster singing up front. Cheshunt Boys` Club was a favored gig around `61. He then enjoyed initial success as a member of The Roulettes (1962-1967), who, in addition to a recording career of their own, backed the popular music singer Adam Faith on tour and on record. After the demise of the Roulettes, Henrit briefly (1968) worked with Unit 4 + 2, an association which went back to his session drumming on their biggest hit, "Concrete and Clay" (1965).

In late 1968, Henrit teamed up with fellow ex-Roulette Russ Ballard, Kink-to-be Jim Rodford and ex-Zombies keyboard player Rod Argent to form Argent, and remained with them until the band ended in 1976. After a brief spell with Rodford and John Verity as Phoenix, Henrit`s post-Argent career included work with a number of artists, including Charlie, after their 1978 tour opening for The Kinks, and Ian Matthews.

As a session drummer, he worked with The Who vocalist, Roger Daltrey, and was present on Dave Davies` Glamour (1981) and Chosen People (1983) solo albums. He also worked regularly with the GB Blues Band which, in addition to Rodford, included former members of the Mike Cotton Sound.

Henrit replaced the long-serving drummer of The Kinks, Mick Avory, after Avory`s departure in July 1984. He worked with the act until their seemingly final demise in 1996. He was the obvious choice to replace Avory, because he and Rodford had already proven to be a capable and compatible rhythm section, and his previous ties with Dave Davies and with other musicians, who had augmented The Kinks over the years.
