Julius Jacobson (1922 – March 8, 2003) was an American socialist writer and editor who edited Anvil, New International, and New Politics, all publications in the Third Camp tradition of socialism, a democratic Marxist tradition sometimes called "Shachtmanite" after its significant theorist, Max Shachtman.
Drafted into military service during World War II, he saw combat in Europe and participated in the liberation of Paris.
Like Hal Draper, Jacobson was opposed to the merger of the ISL into the Socialist Party of America and to Shachtman's drift toward the right politically.
Unlike Draper, he did not turn his energies toward creating a new socialist group, but rather into the creation of an independent journal, New Politics, in 1961, together with Phyllis Jacobson.
In addition to his work published in Anvil, New International and New Politics, Jacobson contributed to the following books: The American Communist Party.
