Horace Raymond Knight OAM (1 December 1915 – 6 June 1990) was a South Australian-born businessman (independent grocer) and philanthropist.

On Knight's return, he began building a chain of self-service supermarkets starting in Prospect and subsequently in Salisbury and Elizabeth branded Foodland, Cheap Foods, or Half Case.

Horrie was well known for providing employment and generally being active in the community as he devoted a lot of time & money to local charitable organisations, namely Rotary.

In addition to his work with Rotary, Horrie was also a founding member of the Elizabeth & Districts Foundation, now known as the United Way (North), which is the largest non-government fund raising/giving organisation in South Australia.

Knight Memorial Trust was established to award individuals or groups who have made an outstanding achievement in the areas of education, arts, literature, music, athletics, and healthy amateur sport.
