Samuel Pomeroy Colt (January 10, 1852 – August 13, 1921) was an industrialist and politician from Rhode Island.

His mother was a member of the large and wealthy DeWolf family, many of whom had profited from the slave trade and related businesses.

In 1881 Colt was elected Attorney General of Rhode Island and was re-elected to three one-year terms.

In 1903, he ran for governor of Rhode Island as a Republican, but failed to unseat the incumbent Lucius Garvin.

In 1905, believing that incumbent Republican Senator George P. Wetmore was not going to stand for reelection, Colt announced his candidacy.

The ensuing contest between Colt, Wetmore and Democrat Robert Hale Ives Goddard resulted in 81 deadlocked ballots cast by the General Assembly over four months in 1907 and a vacant seat in Rhode Island's delegation to the 60th Congress.

Colt died August 13, 1921, of complications from a stroke at Linden Place, the family home in Bristol.
