William Patrick Wood (March 11, 1820 – March 20, 1903) was the first Director of the United States Secret Service. He was the son of James Wood and Margaret Turner.

He was sworn in on July 5, 1865 by Secretary of the Treasury Hugh McCulloch. He then headed the newly formed Secret Service for four years until he resigned in 1869. Wood was a veteran of the Mexican-American War and was once Keeper of the Old Capitol Prison. He was considered the best in battling financial crime, and within a year of its founding, the Secret Service had arrested over 200 counterfeiters. He died on March 20, 1903, and was buried in the Congressional Cemetery in Washington, D.C.
