Terrence William "Blondie" Chaplin (born 7 July 1951) is a South African singer and guitarist from Durban, where he played in the band the Flames in the mid to late 1960s.

For the Beach Boys, it was a period in which long-time member Bruce Johnston had departed the band, and one-time leader Brian Wilson's participation in the group was very limited.

The Bridges to Babylon album lists Chaplin's credits as backing vocals, tambourine, piano, bass guitar, percussion, shakers, and maracas.

Chaplin is the vocalist, songwriter, and lead guitar player with Skollie, a band formed with fellow South Africans Keith Lentin on bass and Anton Fig (of the CBS Orchestra) on drums.

On 29 September 2017, Big Noise's Al Gomes and Connie Watrous presented a plaque from Roger Williams University to Chaplin at The Zeiterion Theatre in New Bedford, Massachusetts.

Chaplin's response to the sold-out audience at the "Brian Wilson Presents Pet Sounds" show: "I played a lot in these parts in 1971, and it's nice to be remembered this way."

The concert was the first-ever appearance of Chaplin as well as Fataar as official members of The Beach Boys, essentially changing the band's live and recording line-up into a multi-cultural group.
