The Poland international has made the move to London for an undisclosed fee, becoming the 'Hammers' third signing after Ryan Fredericks and Issa Diop.
Fabianski has decided to make the change following Swansea's relegation to the Championship last season and is looking forward to continuing his Premier League career in Claret and Blue.
He told the club's official website: "West Ham is a massive club so I’m really happy to be joining at such an exciting time here. I will do my best on and off the pitch to help the team to achieve the best results possible and can’t wait to start this new chapter of my career".
The Hammer's director of football, Mario Husillos, also had his say: "Lukasz is an experienced and established Premier League goalkeeper, with great quality that he has shown at both domestic and international level.
“He fits perfectly the mould of the modern goalkeeper, with excellent agility, presence and distribution, and will bring strong competition to the position.
“Of course, at this moment, Lukasz is fully focused on the World Cup finals with Poland. We wish him all the very best out in Russia and look forward to welcoming him upon his return to England later this summer".
Fabianski has been in England since 2007, making 78 appearances for Arsenal and 150 for Swansea, as well as being capped 45 times internationally.
