Molinari, who made his debut in the 2010 edition when Europe regained the trophy in Wales, joins brother Edoardo Molinari, Spaniard Jose Maria Olazabal, Belgian Nicolas Colsaerts and Denmark's Thomas Bjorn as vice captains.
"I started the year hoping to be there as a player, but it is still a great honour to be there as a vice captain," Molinari, who won the 2018 British Open, said.
The United States won the last Ryder Cup in Wisconsin last year.
Europe have not lost a Ryder Cup on home soil since a 15-13 defeat at The Belfry in England in 1993.
The Ryder Cup will be held from Sep. 26–Oct.
