William Henry Wilson (December 6, 1877 – August 11, 1937) was a Republican lawyer and member of the United States House of Representatives from Pennsylvania.

He graduated from the law department of the University of Pennsylvania in 1898 and was subsequently admitted to the bar in 1899.

He was then elected to two terms in the Pennsylvania House of Representatives and served from 1913 until his resignation on December 28, 1915.

The seat was open because its previous representative, Republican James M. Beck, resigned in protest of the New Deal.

However, two years later, McGranery ran again and defeated Wilson, riding off the coattails of the very popular Franklin D. Roosevelt.
