Abraham Jacob Watson (May 8, 1924 – May 12, 2014) was an American race car builder and chief mechanic.
He served in the United States Army Air Forces during the Second World War, training as a B-17 navigator.
Watson's first win as a car builder came in 1956 when Pat Flaherty drove the John Zink entry to victory in that year's Indianapolis 500.
Watson had won the previous year as a crew chief for Bob Sweikert.
For many years, Watson and his family would spend the racing season in Indiana, and the off-season in California.
