The National Airlines Open Invitational was a professional golf tournament in south Florida on the PGA Tour.

It was held in late March in Hialeah at the West Course of the Country Club of Miami in 1969, 1970, and 1971[1] At the time, it was among the richest events on tour, with a $200,000 purse and a $40,000 winner's share.

In 1972, it was replaced on the schedule by the Jackie Gleason Inverrary Classic in Lauderhill, initially a month earlier in late February.

That tournament ended its affiliation with Gleason after 1980 and continues today as The Honda Classic in Palm Beach Gardens.

The other PGA Tour event in the Miami area was the Doral Open, which began in 1962 and was usually played in early March.
