Daniel Amartey (born 21 December 1994) is a Ghanaian professional footballer who most recently played as a defender or midfielder for Süper Lig club Beşiktaş and the Ghana national team.

[29] On 6 March 2021, Amartey scored his first goal for the Foxes in over four years, heading in a late winner to seal a 2–1 away league win over Brighton & Hove Albion.
