Alopecosa fabrilis, known as the great fox-spider, is a species of wolf spider in the family Lycosidae.

[3] Alopecosa fabrilis is a large species which lives at low population densities and is uncommon.

[3] It was thought that the great fox spider could be found in three locations of heathland across the South of England.

[2] It was re-discovered in October 2020 by Mike Waite of the Surrey Wildlife Trust, at a Ministry of Defence training site in the county.

For example, the habitat at Morden Heath in England was an area of open stony ground close to the summit of a hill and on the walls of gullies.
