Loïc or Loick is a male personal forename chiefly used in Brittany, in western France, and in the Breton community in French-speaking countries.

Loïc is a Breton given name, based on Laou, a Breton diminutive of Gwilherm or Gwilhom (as Bill or Liam is to William), with the diminutive ending ig (like Billy). Non-Breton speaking Bretons often think it is the Breton form of the name Louis.

In Provence, in southeastern France, many think that it actually is "the old Provençal form of Louis",^{[citation needed]} in which case it means "famed warrior".^[1]

Another less well accepted derivation is from Loukas, a Greek name meaning "from Lucania", whose usual French form is Luc (see Luke (name)).^[2]
