James Mark Wilcox (May 21, 1890 – February 3, 1956) was a U.S.
Representative from Florida.
He is remembered as the author of the Wilcox Municipal Bankruptcy Act, which became law in 1934, a bill which initially allowed a city in his district, West Palm Beach, to adjust its bonded indebtedness and avoid bankruptcy.
It was later invoked to help New York City avoid bankruptcy in 1972.
