Stewart Edward "Stew" Albert (December 4, 1939 – January 30, 2006) was an early member of the Yippies, an anti-Vietnam War political activist, and an important figure in the New Left movement of the 1960s.

Among the many activities he participated in with the Yippies were throwing money off the balcony at the New York Stock Exchange, the Exorcism of the Pentagon, and the 1968 Presidential campaign of a pig named Pigasus.

His wife Judy Gumbo Albert claimed, according to his New York Times obituary, that this was because he was working as a correspondent for the Berkeley Barb.

In 1970, he ran for sheriff of Alameda County, California, in revenge for "getting my balls sprayed with hot, painful chemicals as a welcome-to-prison health measure" after being arrested in 1969.

Although he lost to the incumbent, Frank Madigan, Albert garnered 65,000 votes, in an ironic twist, in a race with the sheriff who had supervised his earlier incarceration during the Vietnam Day Committee anti-draft protests in downtown Oakland.
