The 27-year-old has signed a five-and-a-half year contract with Celta Vigo.
“The attacker is now a Celta Vigo player after passing a medical and signing his contract,” Celta said in a statement on their website.
Beauvue scored eight goals in 29 games since joining Lyon from Guingamp in July and becomes Celta’s second signing of the January transfer window.
“He is a very good footballer, very direct and quick,” said Celta coach Eduardo Berizzo.
“He will adapt quickly and feel comfortable in our system.”
