William Frank McCombs (December 26, 1876 – February 22, 1921) was an American lawyer and politician who served as chair of the Democratic National Committee from 1912 to 1916.

[2] Once nominated, Wilson made him chairman of the Democratic National Committee and essentially his "campaign manager."

In 1913, McCombs was offered the position of United States ambassador to France, but turned it down for financial reasons.

[6] McCombs was the Democratic nominee in the 1916 United States Senate election in New York but was defeated by Republican William M. Calder.

In poor health, McCombs died in Greenwich, Connecticut, on February 22, 1921, leaving behind an incomplete memoir, which was published as Making Woodrow Wilson President.
