Östgöta nation, Student nation in Uppsala, Sweden

Östgöta nation is a student nation in Uppsala housed in a yellow building at Trädgårdsgatan 15 that offers study areas, a library, dining facilities, and social spaces. The building also functions as a gathering place with a pub and bar for evening social activities.

The nation was founded in 1646, making it one of the oldest institutions of its kind at Uppsala University. The current building dates to 1885 and underwent major renovation in 1996.

The nation's student pub, Tages, opened in autumn 2000 and is named after Tage Danielsson, a member in the 1950s who staged the legendary spex Gustav Hasa. Its café, Hattstugan, is named after Hatte Furuhagen and is known for its waffle buffet. The nation has staged an annual spex since 1843, still performed in verse.

The building at Trädgårdsgatan 15 has had a lift and accessibility-adapted rooms since 2010–2011. The student-run café Hattstugan serves a waffle buffet on Tuesdays to Fridays from 11:00 to 15:00, with a Saturday café on Saturdays. The evening pub Tages opened in autumn 2000.

The building was designed by Carl August Kihlberg, the architect behind Casa Rosada in Buenos Aires. It was inaugurated in 1885 by King Oscar II, the nation's first honorary member. The basement pub, opened in the early 1990s, was named Tages Källare after Tage Danielsson, who staged his legendary spex Gustav Hasa there in 1951.
