The Manchester City defender played every minute for England in Germany as the Three Lions finished runners-up.
It is the second time in succession Walker has made the team of the tournament, having done so in 2021 when England were beaten by Italy in the final at Wembley.
The team of the tournament was picked by a panel of 12 "technical observers" including David Moyes, Ole Gunnar Solskjaer and Rafa Benitez.
Marc Cucurella (Chelsea), William Saliba (Arsenal), Rodri (Manchester City) and Manuel Akanji (Manchester City) were the players chosen from Premier League clubs.
Lamine Yamal, who won the young player of the tournament award, was named alongside Spain team-mates Nico Williams, Dani Olmo and Fabian Ruiz.
Jamal Musiala, who scored three goals for hosts Germany before their quarter-final exit to Spain, was named in attack while AC Milan goalkeeper Mike Maignan completed the XI.
