Ronald David Wood (born 1 June 1947) is an English rock musician, best known as an official member of the Rolling Stones since 1975, as well as a member of Faces and the Jeff Beck Group.

Wood began his career in 1964, playing lead guitar with several British rhythm and blues bands in short succession, including the Birds and the Creation. He joined the Jeff Beck Group in 1967 as a guitarist and bassist, playing on the albums Truth and Beck-Ola. The group split in 1969, and Wood departed along with lead vocalist Rod Stewart to join former Small Faces members Ronnie Lane, Ian McLagan and Kenney Jones in a new group named Faces with Wood now primarily on lead guitar. The group found great success in the UK and mainland Europe from the early days on, but only reached major fame in the US during their last year of existence, 1975, with a major tour of the US. Wood sang and co-wrote the popular title track from their final LP, Ooh La La, released in 1973. He also worked extensively on Stewart's first few solo albums.

As Faces began to split, he started several solo projects, eventually recording his first solo LP, I've Got My Own Album to Do, in 1974. The album featured bandmate McLagan as well as former Beatle George Harrison and Keith Richards of the Rolling Stones, a longtime friend of Wood. Soon after Mick Taylor left the Rolling Stones, Richards invited Wood to join them; he did so in 1975, initially temporarily, but became an official member in 1976.

Besides I've Got My Own Album to Do, Wood has recorded several other solo efforts. Now Look was released in 1975 and peaked at No. 118 on Billboard; he also collaborated with Ronnie Lane for the soundtrack album Mahoney's Last Stand. Wood also released Gimme Some Neck in 1979, which hit No. 45 in the US; 1234 was released in 1981, peaking at No. 164. He released Slide on This in 1992, Not for Beginners in 2002, and I Feel Like Playing in 2010. As a member of the Rolling Stones, Wood was inducted into the Rock and Roll Hall of Fame in 1989 and was inducted a second time, as a member of Faces, in 2012.
