Södermanlands-Nerikes Nation (usually called Snerikes) is one of the 13 student nations of Uppsala University. The nation claims its founding to be in 1595 when the original Södermanlands nation was founded, this nation merged with the Nerikes nation in 1805 to form the current nation. Though at the turn of the 20th century its numbers were as low as 100 members, there are currently around 5,000 students as members.

Snerikes is unique amongst student nations in being not entirely open to all students. Swedes must be from or have close family relations to the Snerikes catchment area to join. This requirement is waived for foreign students; Snerikes is in fact a popular nation for foreign students.

Buildings 
The nation currently owns several properties in the Rosendal city block in the historic Fjärdingen quarter west of the river in central Uppsala, as well as in the Triangeln block in the Kungsgärdet area. The Rosendal city block contains the main nation building, several offices, student housing, rental apartments and business spaces, while Triangeln solely consists of student housing. Members of Snerikes who are active students are eligible for renting student rooms and apartments for the duration of their studies. In total there are 383 rooms and 85 apartments.

Buildings in the Rosendal city block 
 The Snerikes nation house with the characteristic round tower, built 1896–1897 after 80 years of planning and fund raising. The architect, Gerdt Hallberg, had earlier been employed by the firm responsible for the design of the Riksdag building in Stockholm and designed the nation house in neo-renaissance style. Some of the rooms are named for cities in Södermanland and Närke. The building contains a restaurant and rooms for the nation's social events.
 Stavenowska huset in Rundelsgränd 1, library, reading rooms and student housing, with a book collection founded in the 17th century. Built in 1855 from Johan Otto Larsson's design and named after the historian Ludvig Stavenow, Rector Magnificus of Uppsala University 1918–1929. Stavenow bought the house in 1918. It underwent a major renovation in 1998.
 Engelska villan in Rundelsgränd 3, designed by Axel Bergman for the S:t Eriks clay goods factory, built 1912–13. Contains housing for former students of the nation.
 Backmanska huset, Rundelsgränd 3B, the oldest wooden house in Uppsala, built in the 1620s. The first owner was librarian Johannes Bureus. It belonged to various high officials until the 1900s and was acquired in 1956 by Snerikes. It was one of few surviving wooden structures in the area after the great fire of 1809 and became a protected building in 1993. After a renovation in 1995–96 it presently contains the Snerikes housing office.
 Rosendals matsalar, Rundelsgränd 3C. Originally built in 1792, destroyed in the great fire of 1809 and rebuilt in 1819. Acquired by the nation in 1966. Renovated in 2010 and presently occupied by student housing and commercial spaces.
