Feliceni (Hungarian: Felsőboldogfalva, Hungarian pronunciation: [ˈfɛlʃøːboldoɡfɒlvɒ], meaning "Upper Village of the Blessed", referring to the Virgin Mary) is a commune in Harghita County, Romania, in the vicinity of Odorheiu Secuiesc.

It forms part of the Székely Land, an ethno-cultural region in eastern Transylvania.

The territory of Northern Transylvania remained under Soviet military administration until March 9, 1945, after which it became again part of Romania.

The village was first mentioned in 1505 as Lengenfalwa when a certain Balthasar was elected "seat judge" at Udvarhely.

In 1899, the ethnonym Székely was added to the Hungarian place-name in order to distinguish the locality from another Lengyelfalva (now: Košická Polianka) of the historical Kingdom of Hungary.
