The left-back, 31, has signed a two-year contract at Molineux, with Wolves paying the French side a £1.78million fee. Marçal was at Lyon for three years, helping them reach the Champions League semi-finals last season.
"Having played over 280 games in top leagues, as well as Champions League football, Marçal will add a huge amount of experience to our young team,"
said Wolves executive chairman Jeff Shi.
"He is a player with the technical ability to be able to contribute in the build-up play from the back, all the way through to threatening the opposition in the final phase."
“He possesses good pace and has a great work ethic, to work up and down the football pitch. Defensively he is very solid and will add to our group with his ability in the air as well.

“Of course, because of his nationality, Marçal was subject to a work permit application, and I am delighted that the panel shared our view on the player’s quality and how he can help Wolves.
Marçal is a product of Brazil"s Gremio academy system, which has been responsible for bringing through some of the biggest names in Brazilian football, including Ronaldinho and Emerson.
He is expected to provide Nuno Espirito Santos with proper experience and versatility at the back. He can also play as a right-back and many say he could be slotted in as a replacement for Matt Doherty who joined Tottenham recently.
Since joining Lyon in 2017, Marçal featured 75 times for Les Gones in all competitions. He failed to hit the back of the net once but recorded five assists in that time.
