Don Preston (born as Donald Ward Preston, 21 September 1932, Flint Michigan) is an American singer, pianist, synthesizer and keyboard player, best known as member of the Mothers of Invention between 1967 and 1969.
Don Preston came from a family of musicians. He fulfilled his military service at Trieste, Italy, sharing a room with Buzz Gardner. He played piano in Herbie Mann's band. Throughout the 1950s he played with musicians like Nat King Cole, Paul Bley and Carla Bley.
By the 1960s he experimented with electronic keyboards. When he met Zappa he described him as: "(...) kind of a nerd, but he was smart enough to disguise that by street talk and being into R&B.". Preston played with the Mothers from 1967 until 1969, where he can be heard on the albums Absolutely Free, We're Only In It For The Money, Cruising With Ruben & The Jets, Uncle Meat, Burnt Weeny Sandwich and Weasels Ripped My Flesh. During the 1970s he can be heard on Fillmore East, June 1971, Just Another Band From L.A., Waka/Jawaka, The Grand Wazoo and Roxy & Elsewhere. Additional performances are available on You Can't Do That On Stage Anymore Vol. 1, You Can't Do That On Stage Anymore Vol. 3, You Can't Do That On Stage Anymore Vol. 4, You Can't Do That On Stage Anymore Vol. 5 and You Can't Do That On Stage Anymore Vol. 6, as well as Playground Psychotics, Ahead Of Their Time, The Lost Episodes, Mystery Disc, Quaudiophiliac, The Ark (BTB), Unmitigated Audacity (BTB), 'Tis The Season To Be Jelly (BTB), Electric Aunt Jemima (BTB), Swiss Cheese/Fire!

Preston appears in the films 200 Motels (The Film), Uncle Meat (The Film), Video From Hell and The True Story Of 200 Motels, where he "changes into a monster" after having a drink, parodying Dr. Jekyll and Mr. Hyde. In Uncle Meat he seduces Phyllis Altenhaus with hamburgers. His monster character was a reference to Dr. Ogo Moto, a character he had created in a series of four films he had made himself.
He is interviewed in Frank Zappa - The Freak-Out List (2010).
Outside his career with Zappa, Preston played keyboard on the soundtrack of Francis Ford Coppola's film Apocalypse Now (1979). He also wrote music for "Eye Of The Tiger" and "Emmanuelle 1: First Contact". He performed on records by John Lennon & Yoko Ono, Flo & Eddie, Eugene Chadbourne, The Residents and Jefferson Airplane.
