Philip Ober (23 March 1902, Fort Payne, Alabama - 13 September 1982, Mexico City) was an American actor.

Ober often appeared in roles as a straight man in farcical circumstances. One of his most memorable stage role was in Lawrence Riley's Broadway hit Personal Appearance (1934) opposite Gladys George. From 1954 to 1967 he frequently appeared in television series. From 1941 to 1959, he was married to actress Vivian Vance, who famously portrayed Ethel Mertz in the TV series I Love Lucy (1951-1957).

He had an important, but brief role, as the UN ambassador in Alfred Hitchcock's North by Northwest (1959) whom Roger Thornhill (Cary Grant) meets, in order to clarify who had occupied his mansion. He also played Deborah Kerr's unsympathetic husband in the film version of From Here to Eternity (1953).

He had a recurring role as Gen. Wingard Stone in the very early episodes of long-running NBC situation comedy I Dream of Jeannie.

Philip Ober's bald head, stern bearing and booming voice made him a natural for the roles of business executives, high-ranking military officers and other authority figures he played so well. A Princeton University graduate, Ober spent years as an advertising executive for several different national magazines before switching careers to acting. He spent many years on Broadway and in stock companies before breaking into films. His best remembered roles would probably be that of the murder victim who dies in Cary Grant's arms in North by Northwest (1959) and the bullying officer whose wife is having an affair with his subordinate, Burt Lancaster, in From Here to Eternity (1953). He also did much television work, including appearances on his wife's show, "I Love Lucy" (1951) (he was married to Vivian Vance at the time). He retired from acting and went into the U.S. diplomatic service, and, while working at the U.S. consulate in Mexico City, died of a heart attack in 1982.
