The name is of somewhat debated origin. One is that it is a Breton form of Louis, however, in the Breton language, ïc usually denotes a diminutive form and thus it would not make sense that it is a form of Louis, and there is no other full Breton name which would fit the mold of Loïc. It has been suggested that it is instead an old Provençal form of Louis which was later borrowed by the Bretons.
Currently, Loïc is the 34th most popular male name in French-speaking, Switzerland, (2010). His rankings in other countries are as follows:
- # 62 (Belgium, 2009)
- # 113 (France, 2009)
