The striker scored 39 goals in 76 competitive games in Germany after moving from Manchester United in 2015, following one season on loan at Real Madrid.
“I am very happy to join West Ham United,” he said. “For me, the Premier League is the best league in the world and when the opportunity came, I was desperate to sign for this club.
“It was not a difficult decision. West Ham is an historic club, and very ambitious – this summer you can see with the players signed that they are looking to have a very good season.
“I’ve had three fantastic years playing in Spain and Germany, but England was really the first big chapter in my career and I am so happy to be back.
“I am desperate for the season to start and to help the team achieve all their objectives.”
Joint-Chairman David Sullivan added: “We are delighted to welcome Javier as the latest fantastic addition to the West Ham United squad.
“Following the arrivals of Pablo Zabaleta, Joe Hart and Marko Arnautovic, he is another top class professional who brings great experience and quality to the Club.
“He has a proven goalscoring record in the Premier League, La Liga and the Bundesliga, as well in the UEFA Champions League and at international level with Mexico.
“We now have some fantastic options in attacking positions and, like all West Ham fans, I am looking forward to seeing Javier score goals in a claret and blue shirt next season.”
Chicharito became Mexico's all-time leading goalscorer in May, recording his 47th international goal during a friendly against Croatia.
