James Joseph Lanzetta (IPA: [lanˈtsetta]) (December 21, 1894 – October 27, 1956) was an engineer, an attorney and a politician, a member of the United States House of Representatives from New York for two non-consecutive terms, the first from 1933 to 1935 and the second between 1937 and 1939, and a justice in city court.

Lanzetta joined the United States Army for World War I as a private in Company C, 302nd Engineers, and he was later a sergeant first class in the 1st Air Service Mechanics Regiment.

With the help of the Tammany Hall boss Jimmy Hines,[1] Lanzetta was elected as a Democrat to the 73rd Congress.

After Lanzetta's 1938 defeat for re-election, he was appointed as legislative representative or counsel for Puerto Rico in Washington, D.C.

Although he had never visited the island, he proved popular with its political leaders of all parties and with the residents of Puerto Rico.
