The 25-year-old centre-back has agreed to a move to Craven Cottage on a five-year deal.
Diop made 121 appearances for the Hammers during his four-year stint at the club and was a key figure in their run to the Europa League semi-finals last season.
“I’m thrilled to join Fulham; I hope it’s going to be an excellent chapter of my career,” Diop told the Fulham website.
“It’s all official now, so I’m happy. I want to train with the team now, and let’s get to work.”
Diop, representing France at the youth level, moved to the Hammers from his boyhood club Toulouse in the summer of 2018.
“I’m very excited that we’ve brought Issa Diop to Fulham,” vice-chairman Tony Khan said.
“Issa is a talented and imposing defender whom we’ve pursued for a long time, and his experience and formidable presence will be important to our squad in this Premier League season and for us to build a bright future in the years ahead.”
