William Gardner Angel (July 17, 1790 – August 13, 1858) was an American politician and lawyer who served two terms as a U.S. Representative for New York's 13th congressional district from 1825 to 1827, and from 1829 to 1833.
In 1809, Angel was heard as a witness at a trial where William Dowse, a lawyer from the county seat Cooperstown, appeared for the defense.
After Dowse's death, Angel continued to study law with Farrand Stranahan, and in 1816 entered the office of William Welton in Sherburne, Chenango County, New York.
At this time, Martin Grover studied law with Angel, first in Burlington, then in Hammondsport.
Angel died on August 13, 1858, in Angelica, Allegany County, New York; and was buried at the Until the Day Dawn Cemetery there.
