Chidozie Obi-Martin (চিডোজি ওবি-মার্টিন), commonly known as Chido Obi, is a Danish professional footballer who plays as a forward for Premier League club Manchester United.

Obi was born in Glostrup, a Copenhagen suburb, to Nigerian Igbo parents.

Eligible to represent Denmark, Nigeria or England at international level, Obi made five appearances in late 2022 for Denmark's under-16 team, before switching allegiance to England. He represented England twice at under-16 level in February 2023, against Cyprus and Scotland. However, in April of the same year he returned to the Danish under-16 team, scoring twice in three appearances. His prolific goal-scoring form earned him a call-up to the Denmark under-17 team, and he started Denmark's 2024 UEFA European Under-17 Championship qualification campaign with two goals in his first three games.
