Băile Felix (Hungarian: Félixfürdő) is a thermal spa resort near the commune of Sânmartin in Bihor County, Transylvania, Romania. Băile Felix is at a close distance to Oradea, a major city in western Romania.
Thermal springs were valued in the eighteenth century by the monk Félix Helcher of the Monastery of Klosterbruck (de) in Moravia, administrator of the Váradszentmárton (today: Sânmartin, Romania) monastery. Between 1711-1721 the first treatment facilities were organized under the name of Félixfürdő (in Romanian: Baia lui Felix). Félix Helcher died in 1737. In 1885 a new spring, with a temperature of 49 °C, was found.
The thermal springs were discovered around 1000, or around 1200, or according to other experts, only in 1700. The only fact agreed by all experts is the appearance of the first buildings in this resort: between the years 1711–1721.
In 1920, the commune became part of Romania, in 1940, it was given back to Hungary. After World War II, again it become part of Romania.
In 1948 Sanmartin monastery area was nationalized by the communist authorities. Several recreational bases, including the one belonged to Securitate, were built on the nationalized land. The Premonstatens Order claims it latter. On April 2, 2014, the HCCJ (Higher Court of Cassation and Justice) ordered the transfer of the filed case from Oradea Court to the Giurgiu District Court, where it is now. Other requests of the Premonstratens Order on retrocession the Băile Felix lands are in progress at HCCJ.
