Francis Hamilton "Fran" Striker (August 19, 1903 – September 4, 1962) was an American writer for radio and comics, best known for creating the characters the Lone Ranger, the Green Hornet, and Sgt.

In 1929, he moved to WTAM in Cleveland, Ohio, where he served as announcer and continuity writer and wrote his first radio drama script, a biography of Stephen Foster.

Lured back to WEBR as station manager, Striker wrote material ranging from skits to half-hour mysteries and Western scripts.

He began a long association with station owner George W. Trendle and radio station WXYZ in Detroit, which was trying to make a name for itself as a producer of radio drama, creating and writing the early series Thrills of the Secret Service, Dr. Fang, and Warner Lester, Manhunter (which introduced Mike Axford, later a supporting character on The Green Hornet).

Late in 1932, Striker began working on The Lone Ranger; his earliest scripts were largely reworked from his earlier series Covered Wagon Days.

In exchange for selling the rights, Striker accepted a writing contract that would provide for his family and offer job security throughout the Depression.

In 1954, Trendle sold The Lone Ranger rights to the Wrather Corporation for three million dollars, a record sale at the time.

Striker's later work included stints on the television versions of The Lone Ranger and Sergeant Preston of the Yukon, which were initially being produced while the radio series were still on the air.
