Cârța (Romanian: [ˈkɨrtsa]; Hungarian: Csíkkarcfalva or Karcfalva [ˈ(t͡ʃiːk)kɒrt͡sfɒlvɒ]) is a commune in Romania, located in Harghita County.

It lies in the Székely Land, an ethno-cultural region in eastern Transylvania.

The commune is composed of two villages: Cârța (Karcfalva) and Ineu (Csíkjenőfalva).

The village belonged to the Székely seat of Csíkszék, then from 1876 until 1918 to the Csík County in the Kingdom of Hungary.

After Soviet occupation, the Romanian administration returned and the village became officially part of Romania in March 1945.
