The Science Fiction Foundation is a Registered Charity established 1970 in England by George Hay and others.

For much of this period the Director of the Foundation was Malcolm Edwards, who later moved to Gollancz, and then Orion.

SFF publishes the journal Foundation: The International Review of Science Fiction three times a year and occasional critical works under the general title Foundation Studies in Science Fiction.

The SFF provides a scientific speaker for the annual Eastercon, under the general title of the George Hay Memorial Lecture.

The SFF and the British Science Fiction Association hold their annual general meetings jointly in either May or June.
