The Fremington Hagg Hoard is a hoard of Roman horse harness fittings found in Fremington Hagg, near Reeth, North Yorkshire in the early 19th Century.

[2] The hoard was discovered before 1833, when the first objects were donated to the Yorkshire Museum.

[3] In 1880 A. W. Franks donated a portion of the hoard to the British Museum.

[2] These are all harness fittings (horse gear) - decorative elements used on reigns and other straps.

A further 28 objects in the Yorkshire Museum are associated with the hoard, but were considered by Graham Webster as not belonging to it - these include a scabbard mount, a chape, terret rings, studs, and other mounts.
