The Colonial National Invitation was a men's tennis tournament played at the Colonial Country Club in Fort Worth, Texas, United States from 1962 to 1973. The club hired Tut Bartzen as a tennis pro and made him responsible for hosting the tournament. The inaugural edition in 1962 was an amateur-only event. In 1967 it became a professional tournament, which meant that amateurs could not compete. The total prize money for the tournament that year was $15,000 and the first-prize, won by Rod Laver, was $1,700. The following year, 1968, a women's professional event was added which was won by Ann Haydon Jones. The tournament was part of the WCT Tour from 1970 to 1973 and was held on outdoor hard courts.
