Tickencote Marsh is a three hectare biological Site of Special Scientific Interest west of Tickencote and Great Casterton in Rutland.

[1][2] This site in the valley of the River Gwash is a base-rich grazing marsh, a habitat which is becoming increasingly rare as a result of drainage and a decline in grazing.

Common flora include lesser pond-sedge, marsh horsetail and jointed rush.

[3] The site is private land with no public access.
