Sherman Willard Tribbitt (November 9, 1922 – August 14, 2010) was an American merchant and politician from Odessa in New Castle County, Delaware.

In early 1945 he was aboard the destroyer USS Frost in the North Atlantic when his unit received a Presidential Citation for sinking five U-boats.

Tribbitt prevailed in a difficult convention contest for the nomination and was elected lieutenant governor of Delaware in 1964, defeating William T. Best, a State Representative from Rehoboth Beach.

Like Terry, he was narrowly defeated in the 1968 Republican landslide by Eugene Bookhammer, a State Senator from Lewes.

There was an effort to levy a large tax on the one oil refinery in the state, but that was derailed when the owner, J. Paul Getty, threatened to close it.

Tribbitt sought a second term in 1976, but, largely because of the unresolved financial situation, lost to U.S. Representative Pete du Pont.

Tribbitt made another bid for governor in 1984, losing the Democratic primary to former Delaware Supreme Court justice William T. Quillen.

After leaving office he worked with the Delaware River Basin Commission and the Diamond Group consulting firm.

Jack Markell, Governor of Delaware at the time, ordered state flags lowered to half staff in Tribbitt's honor.
