William Evans Crow (born March 10, 1870) was a Republican politician who represented Pennsylvania in the United States Senate. Serving as a senator for a single term, he held office from October 17, 1921, to March 3, 1923. During this period, he was a historical member of Congress associated with the Republican Party.

Crow’s tenure in the Senate was as a former senator for the state of Pennsylvania, and he did not represent a specific congressional district, as is customary for members of the Senate. While details of his committee assignments, office room, and official contact information are not provided in the available record, his service from 1921 to 1923 places him within the post–World War I era of American politics. His career in the Senate is documented under the bioguide ID C000938.
