William Baruch Clagett (August 12 or 13, 1854 – July 25, 1911)[1] was a Maryland tidewater tobacco farmer.

[2] In 1892, he was appointed as tobacco inspector[note 1] by Governor Frank Brown; he also served as chair of the Democratic State Central Committee.

[3] Instead, Clagett entered politics when elected as a state senator from Prince George's County in 1897, serving from 1898 to 1901 and 1906 to 1910.

Clagett died of Bright's disease and was interred at Trinity Protestant Episcopal Church, in Upper Marlboro, where he had served as a vestryman.

[1] After descendant Charles Clagett's death in 1971, with his will having made clear that he wanted the property used for educational purposes, his estate bequeathed the farm's 283 acres (115 ha) to the Chesapeake Bay Foundation in 1981.
