Gil Green (September 24, 1906 – May 4, 1997) was a leading figure in the Communist Party of the United States of America until 1991. He is best remembered as the leader of the party's youth section, the Young Communist League, during the tumultuous decade of the 1930s.

Gil Green was born Gilbert Greenberg in Chicago. His parents were working class Jewish immigrants from the Russian Empire. Green's father, who worked as a tailor, died when Gil was about 10, leaving his mother to support the family as a garment worker.

Green was a successful student, graduating high school in the spring of 1924 as his class president and valedictorian.

Green joined the Young Workers League, youth section of the Communist Party, USA, in 1924. He went to work full-time for the Young Workers (Communist) League in 1927 when he was named the organization's district organizer for Chicago.

In 1928 Green spent several months in Massachusetts raising funds for striking workers embroiled in the 1928 New Bedford textile strike. He was moved to New York City by the Communist Party the following year to work at national headquarters as a full-time youth section functionary. He worked as the editor of the party's youth newspaper, Young Worker, and in 1930 was named New York state organizer for the renamed Young Communist League (YCL). In 1931 he was promoted to the position of national secretary of the YCL. On January 15, 1931, William Albertson was to serve as secretary of a "Provisional Anti-War Youth Committee" of New York State to hold a rally for a Liebknecht Memorial and Anti-War Demonstration at the Star Casono at Park Avenue and 117 Street in Manhattan; CPUSA executive William Weinstone and YCL leader Green were to attend.

Green was named one of three communist youth leaders named to the Executive Committee of the Communist International in Moscow in 1935. In that capacity he attended the 6th World Congress of the Young Communist International (YCI), which elected him to the Executive Committee and Secretariat of that body.

Green remained a prominent youth leader of the American Communist Party throughout the depression decade, attending the 1936 World Youth Congress held in Geneva and serving as one of three YCI delegates to a meeting with the rival Socialist Youth International that drew up a unity agreement with regards to aiding the Spanish Republic in the ongoing Spanish Civil War. Green was also a delegate to the 1938 World Youth Congress held in the United States at Vassar College.

Leaving the communist youth movement at the end of the decade, Green was selected as a member of the National Board of the Communist Party, USA. He served as the party's top official, district organizer, of the key party district of New York from 1941 to 1945 and was vocal in his support of CPUSA General Secretary Earl Browder. In 1943, Green convinced Bella Dodd to join the Party openly, first by filling a local New York government position left open by Si Gerson (who was enlisting in the Army). Following the fall of his patron in 1945, Green was moved out of New York to become district organizer in Chicago to become the Illinois State Secretary of the CPUSA.
