Henry Manners Katzman (March 2, 1912 – May 11, 2001) was an American musician, composer, painter, and one of the founders of Broadcast Music Incorporated (BMI).

The son of bandleader Louis Katzman, he grew up in New York City in a musical household and quickly took to the piano as his instrument of choice.

ASCAP had focused solely on big band music and refused to publish works in such categories as blues, country, jazz, and folk.

He also composed soundtrack music, including "Thumper Song" and "Twitterpated" for the original Bambi animated film.

As a pianist, he played with George Gershwin and accompanied Irène Bordoni, Fred Allen, and Jan Peerce.
