Ole Gunnar Solskjaer's side triumphed 3-2 over the Reds in a see-saw Old Trafford clash.
Mo Salah gave Liverpool a first half lead, only for the Red Devils' Mason Greenwood to level soon after.
Marcus Rashford and Salah exchanged goals in the second half, before Bruno Fernandes' 78th minute free-kick settled the tie.
The Hammers, who eased to a 4-0 victory over Doncaster Rovers in the fourth round on Saturday, will now head to Old Trafford for a midweek game in the week commencing 8 February.
West Ham last faced the Red Devils in the FA Cup in the 2015/16 season, when the Manchester side prevailed following a replay in the quarter-final tie.
