The 27-year-old forward, capped 18 times for the Pumas, linked up with the Warriors this season after representing Argentina in the Rugby Championship.
At 6ft 8in and weighing in at 115kg, Galarza will provide Gloucester with additional second row options.
"We're delighted to have secured Mariano's services, as his qualities will complement the players we already have in place and give us some genuine options in the second row," Gloucester rugby director Nigel Davies said on Wednesday.
He added: "Having spoken with Mariano, he is excited at the prospect of becoming a Gloucester player and is looking forward to becoming part of what is shaping up to be an exciting squad of players.
"I believe this gives us plenty of strength and depth in a hugely important area of the squad as we seek to establish a powerful forward platform for next season. Mariano is an experienced, physical operator and his signing is another statement of intent for us.”
Galarza, who was involved in the 2011 Rugby World Cup, spent time with Leinster in 2010-11, before returning to his homeland to play for the Pampas XV in the Vodacom Cup.
