Ralph Perry Forbes (March 12, 1940 – June 10, 2018) was an American Christian Identity minister, neo-Nazi, and perennial candidate in Arkansas. A former US Marine, he was a member of the American Nazi Party throughout the 1960s. Starting in 1963, Forbes led the ANP's California branch, the Western Division, until his expulsion in 1967. In 1965, party leader George Lincoln Rockwell enlisted him to become the ANP's Christian Identity minister in an effort to appeal to a wider American audience; Forbes mixed neo-Nazism with Christian Identity ideology. His religious views created conflict between him and the otherwise largely secular organization.

As leader of the Western Division he was involved in a dispute with the city of Glendale, California, in 1964 and 1965. After Rockwell was murdered in 1967, Forbes, a Rockwell loyalist, left the ANP after a power struggle within the Western Division. He moved to London, Arkansas, where he continued his Christian Identity adherence and was active in local politics. In the 1970s, he founded the Sword of Christ Good News Ministries, a Christian Identity group. He was involved in an effort to mainstream the Ku Klux Klan in the 1980s. He ran for office several times, and was the campaign manager for David Duke's 1988 presidential campaign with the Populist Party.

Forbes was also known for filing several high-profile lawsuits. In 1986, he sued, among others, the Arkansas Department of Education and Satan in an effort to stop the Arkansas school system from celebrating Halloween. Federal judge George Howard Jr. agreed to hear the case, and eventually dismissed the suit. A 1992 lawsuit by Forbes after he was excluded from a television debate resulted in the Eighth Circuit Court of Appeals requiring public broadcasters to declare a "viewpoint-neutral" reason for excluding candidates; this was appealed to the Supreme Court of the United States, which decided against him in Arkansas Educational Television Commission v. Forbes.

Ralph Perry Forbes was born in Milwaukee, Wisconsin, on March 12, 1940. He moved to Flint, Michigan, with his family in his youth. He enlisted in the United States Marine Corps in 1957; Forbes did not graduate from high school, but received his GED after his enlistment. While enlisted in Washington, D.C., he married Karen Paula Wright. Together they had twelve children.

After he left the Marines, Forbes became acquainted with neo-Nazi George Lincoln Rockwell, and joined Rockwell's American Nazi Party in 1960. Initially, he was Rockwell's driver, but by 1961 was one of the leaders of the group. In February 1961, he was dispatched alongside two other stormtroopers (the term for ANP members) to picket the premiere of the film Exodus at the Boyd Theatre in Philadelphia, Pennsylvania; they were greeted by counter protestors and police looking to prevent violence between Nazis and their opponents. It ultimately erupted into violence when, prior to the ANP members arriving, the anti-Nazi protestors mistook a group of unrelated youth for the Nazis and attacked them, leading to the teens being severely injured. When the three actually arrived they had objects thrown at them. In the aftermath of the event, 64 anti-Nazis and the three neo-Nazis, including Forbes, were arrested; the three were charged with inciting a riot, disorderly conduct, and breaching the peace. They were jailed for thirty days, but were acquitted.

In July, when the ANP left a courthouse meeting in their base of operations in Arlington, Virginia, Forbes, the driver, was arrested when he was found to be driving without a registration permit. Unable to pay his $100 bail, he was jailed. When Karl Allen decided to join the ANP, his presence created factional disputes within the group; due to his credentials, beyond what most members of the party achieved, many people feared he was actually a spy as his joining seemed too good to be true. Forbes was one of the members most opposed to him; they later became good friends. In 1962 Forbes marched outside the White House carrying anti-Jewish signs and was attacked.

In April 1963, John Patler, who had previously left the ANP, requested to be readmitted. Forbes despised Patler and was one of the strongest opponents to his re-admittance. When he was eventually readmitted, Forbes immediately resigned, despite Rockwell's pleas. However, at about this time, the leader of the California branch (the Western Division) of the ANP, Leonard Holstein, needed to be replaced after he was jailed; to replace him, Rockwell sought out Forbes. Rockwell asked Forbes to operate the Western Division, and Forbes quickly agreed and returned to the ANP after less than a month. He and his family moved to California, with Forbes announcing his transfer to the west division of the ANP on May 2, 1963. He was a captain within the ANP's ranks. After it helped him get a rally permit in 1963, Forbes had what was described by the Encyclopedia of Arkansas as a "long love-hate relationship with the [American Civil Liberties Union]". He cancelled the rally after he could not pay the required bond.

The Californian branch was noted as particularly contentious. As leader of the Western Division, Forbes led 25 ANP members who donated funds and attended group meetings, with Forbes allowing observer members to attend up to three meetings before they had to become official members. He organized several protests and counter protests against the civil rights movement in particular. One of these was a campaign of disruption against the civil rights group Congress of Racial Equality. Forbes disrupted a CORE rally led by Marlon Brando, jumping in his way waving a sign labeled "Marlon Brando Is a Nigger-Loving Creep"; Brando had no response. In 1964, after Rockwell was unable to attend, Forbes instead gave a speech to an audience of 6,500 at the University of California, Berkeley; the audience largely heckled him. He was a frequent speaker on California college campuses. His recruiting was largely poor.
