Søraust-Svalbard Nature Reserve (Norwegian: Søraust-Svalbard naturreservat) is located in the south-eastern part of the Svalbard archipelago in Norway. The nature reserve covers all of Edgeøya and Barentsøya in addition to a number of smaller islands, including Thousand Islands, Ryke Yseøyane and Halvmåneøya. The reserve is 21,825 square kilometres (8,427 sq mi), of which 6,400 square kilometres (2,500 sq mi) is on land and 15,426 square kilometres (5,956 sq mi) is on water—making it the second-largest preserved area in Norway (including national parks). The reserve has been protected since 1 July 1973 and borders in the north to Nordaust-Svalbard Nature Reserve.

The reserve is dominated by strandlines and patterned ground, although large sections are glaciated. On Edgeøya, many areas have raised beach deposits, giving distinct strandline, and showing whale bones formerly below sea level. The most popular places are Kapp Lee, Diskobukta and Halvmåneøya for tourists. There is an all-year visitation ban on Zieglerøya, Delitschøya, Spekkholmen, Haudegen and large parts of Halvmåneøya.

Traditionally, the area has been used for trapping polar bear and walrus; remains of trapper buildings remain at Ekrollhamna. The reserve contains the most important resting places for walrus in the archipelago. The area also features a lot of reindeer, and is used as a nesting places for birds. On Thousand Islands is a core area featuring red-throated divers, brent geese and Arctic terns. The vegetation is moss tundra, formed by centuries of accumulated reindeer excrement.
