Alex Hay (10 May 1933 – 11 July 2011) was a Scottish professional golfer, golf instructor, writer and a former BBC sports commentator. Hay was best known for his commentating partnership with Peter Alliss where their banter, often displaying humour or wit became regarded by many as the "Voice of Golf". He was a former Ryder Cup referee.

He was the professional at East Herts and Dunham Forest. For 12 years, he was the professional at Ashridge Golf Club between 1964 and 1976.

He co-presented all the major golf tournaments with fellow commentator Peter Alliss during this period and Hay and Alliss were renowned for their great rapport and charisma on television, and enduring friendship outside of the commentary. Hay also provided commentary with Alliss in the Actua Golf video game series, capturing the charm of their television commentary.
Although Hay retired from broadcasting, he remained involved in the professional golf scene. He was noted for his golfing instruction, particularly the techniques of the swing. He wrote numerous works on the subject. His son David, also a golfer, is proprietor of the Galloway's Restaurant in Woburn.
