Crystal Palace manager Roy Hodgson has made the Getafe goalkeeper Vicente Guaita his first capture of the summer.
The 31-year-old, whose contract with the Spanish side expires in just over three weeks' time, has agreed a three-year deal with the Eagles.
In 2017/18 Wayne Hennessey made 27 Premier League starts in goal for Palace and Julian Speroni 11, while in 2016/17 Steve Mandanda was also on the club's books although his time at Selhurst Park was ruined by injuries.
Guaita made more than 100 appearances for Valencia before moving to Getafe four years ago.
Last season Getafe finished eighth in La Liga thanks largely to their fine defensive record. They only let in 33 goals in their 38 matches with only Barcelona and Real Madrid conceding fewer.
Palace chairman Steve Parish said: "We are delighted to sign one of La Liga's best goalkeepers and pleased that we beat off the competition for his signature.
"We very much look forward to Vicente joining in pre-season training and helping us push on in the Premier League."
Crystal Palace finished 11th in the Premier League last season despite losing their first seven matches, failing to score a goal in any of them.
They are 9/4 to secure a top-half finish in the 2018/19 campaign and 11/2 to be relegated.
