The Memphis Invitational was a men's professional golf event played in 1945 and 1946. It was played at the Chickasaw Golf Club each year.
The 1945 tournament drew national attention as Byron Nelson had won 11 straight events on the PGA tour and was going for 12 in Memphis. Amateur Fred Haas won the tournament by five strokes, with Nelson finishing in fourth place, six strokes behind.
