William McCreery (Maryland politician)

William McCreery (1750 – March 8, 1814) was a U.S. Representative from Maryland.

Born in the Province of Ulster in the Kingdom of Ireland, McCreery received a limited education and immigrated to the United States in his youth, where he located in Maryland. He engaged in agricultural pursuits, and was elected as a Democratic-Republican to the Eighth and to the two succeeding Congresses (March 4, 1803 – March 3, 1809). In Congress, McCreery served as chair of the Committee on Commerce. After his tenure in Congress, he resumed agricultural pursuits, and also served as a member of the Maryland Senate from September 1811 until his death at his country home, "Clover Hill", near Reisterstown, Baltimore County, Maryland.
