Young, 32, joined United in 2011 for a deal worth in the region of £18m and has gone on to play 193 games for the Red Devils.
The former Aston Villa winger found himself on the periphery of the United first team under Louis van Gaal but, after being converted to a left-back by Jose Mourinho, has featured more regularly this season.
The club have exercised an option to extend the 31-cap England international’s contract by one year, tying him to the club until 2019.
