Frank Snowden Katzenbach, Jr. (November 5, 1868 – March 13, 1929) was an American jurist and Democratic party politician from New Jersey.

[2] At the Democratic State Convention of 1907, Katzenbach received the party's nomination for Governor of New Jersey.

In the campaign against the Republican nominee John Franklin Fort, both candidates agreed on the creation of a public utilities commission, the enactment of civil service reform, and the adoption of direct primary elections.

[3] The election returns were extremely close, with many newspapers (including The New York Times) announcing the next day that Katzenbach had won.

He died in a Trenton, New Jersey, hospital from sepsis caused by a leg infection.
