The France worldwide joins the Irons on a free transfer having been released by Marseille in November after he attacked a supporter ahead of his side's Europa League match with Vitoria.
Despite being 36-years-old, Evra is keen to keep going however, and, it would seem that one Premier League club is set to take a chance. Among other English clubs interested in the France global are Everton but the player is said to be keen on a move to London.
Disenchanted West Ham fans vented their anger towards owners David Sullivan and David Gold during Saturday's defeat at Brighton.
It also means a return to English football, Evra joined United in January 2005 and would go on to make no fewer than 379 appearances for the record champions, winning five league titles and the European Cup.
He told the official West Ham website: "I'm really happy to be a Hammer, to be back in the Premier League, and I love this game". Boasting a number of players in the left-back position, Evra is no longer the player he even was under Moyes at United. Winston Reid and Angelo Ogbonna are both 29, while Aaron Cresswell - who will contend with Evra for the left-back spot in Moyes' team - is 28. They won't be old journeymen, they will be young players.
He said: "It happened really fast. They won't be 32".
He saw his contract with Marseille get terminated on mutual consent in November.
