Bournemouth captain Neto has signed a three-year contract extension, keeping him at the club until 2026.
The Brazilian goalkeeper has kept four clean sheets in 18 appearances for the Cherries this season.
The 33-year-old joined the Premier League club from Barcelona in August last year, having previously played for Valencia, Juventus and Fiorentina.
"I'm really happy, the welcome from the fans from when I first arrived was unbelievable," he said.
Bournemouth are 19th in the Premier League, two points from safety, and play Fulham on Saturday.
"We will give our 100% to make sure we stay in the Premier League now and always do our best," Neto added.
