Hämäläis-Osakunta

 (HO, colloquially Hämis ) is one of the 15 student nations at the University of Helsinki, Finnish-speaking and established in 1653 at The Royal Academy of Turku. In 1828, the academy moved to Helsinki adopting the name university and Hämäläis-Osakunta moved there along with the other nations. HO represents the historic region of Tavastia (nowadays, roughly Pirkanmaa, Tavastia Proper and Päijänne Tavastia), so it recruits its members actively there. The building of the nation, built in 1931, is located in Kamppi, on Urho Kekkosen katu.

Premises
Hämäläis-Osakunta owns the building Hämäläisten talo ("Tavastians' House" or loosely "Häme House") at Urho Kekkosen katu 4–8, across the street from the Kamppi Center. The first floor of 4 D is rented out to Tavastia Club and the four upper floors are reserved for use by the nation's members. The other staircases (4, 6 and 8) are also rented out by Hämäläisten ylioppilassäätiö (loosely "Häme Students' Foundation"), the foundation in charge for the real property of the nation. The nation has also a summer villa in Hausjärvi.
