Robert O'Brien (April 11, 1908 – February 10, 1987) was a racing driver from the United States. He participated in one Formula One World Championship Grand Prix, the 1952 Belgian Grand Prix.
Career
O'Brien was born in Lyndhurst, New Jersey. He mostly raced sports cars in the US, finishing fourth in the 1952 12 Hours of Sebring in a Ferrari 166 MM shared with Richard Cicurel.
O'Brien later made a few appearances in Europe through his contacts in Belgium.
O'Brien is one of the more obscure drivers to have participated in the Formula One World Championship, and unsubstantiated rumours arose that he was involved with the CIA and operated as a spy. He was later involved in the motor industry in his home state and in New York.
