The 24-year-old Manchester United player was recognised by the Duke of Cambridge for supporting vulnerable children through his free school meals campaign, which saw a change to government policy.
As well as helping them in that way, he hopes this award will spread the positive message that anything is possible.
Rashford's mum Melanie was there for the investiture ceremony at Windsor Castle.

"She asked me I was nervous and I was just like 'no because the award's actually for you'", he said.
