Tarcutta Hills Reserve is a 738 ha nature reserve on the lower western slopes of the Great Dividing Range in central west New South Wales, Australia. It is 427 km south-west of Sydney, close to the Hume Highway, and 15 km south of Tarcutta. It is owned and managed by Bush Heritage Australia (BHA), which purchased it in 1999, and it is listed on the Register of the National Estate. In late 2020, Bush Heritage purchased a 288 ha parcel of land, adjacent to the northern boundary of the reserve, extending the total size of the reserve. The new block of land features a large and healthy example of White Box-Yellow Box-Blakely's Red Gum Grassy Woodland, an ecological community classified as Critically Endangered in NSW.
