George Washington Houk (September 25, 1825 – February 9, 1894) was a lawyer and politician representing Ohio in the U.S. House of Representatives from 1891 until his death in 1894.

George W. Houk was born near Mount Holly Springs in Cumberland County, Pennsylvania, the son of Adam and Catherine (Knisley) Houk. The family moved to Dayton, Ohio in 1827 where George Houk attended the public schools and the E. E. Barney Academy at Dayton. For a number of years Houk taught school while he studied law with Peter P. Lowe. George W. Houk was admitted to the bar in 1847, commencing practice in Dayton.

He married Eliza Phillips Thruston (23 October 1833 – 31 August 1914), daughter of Robert A. and Mary (Phillips) Thruston, both of locally prominent families. They had five children.

In 1861, he became a law partner of John A. McMahon, who had previously been a law partner of Clement Vallandigham. He remained in that partnership until 1882.

Houk was elected a member of the Ohio House of Representatives, serving from 1852 to 1854. He was a delegate to the Democratic National Convention in 1860 supporting Stephen A. Douglas and a delegate again in 1876. He was defeated for circuit judge in the Ohio Second judicial circuit in 1884.

He died suddenly in Washington, D.C. during his second term. Paul J. Sorg was elected to fill the vacancy in a special election in May 1894.

George Washington Houk and his wife are interred in Woodland Cemetery, Dayton, Ohio.
