Marlos Moreno Durán (Spanish pronunciation: [ˈmaɾlos moˈɾeno]; born 20 September 1996) is a Colombian professional footballer who plays as a forward for Categoría Primera A club Atlético Nacional

Moreno began his career with Atlético Nacional before joining Premier League side Manchester City for £4.75 million in 2016. During a six-year spell with City he failed to make a first team appearance and was never selected for a matchday squad, instead spending his tenure in with the Blues on loan at Deportivo La Coruña, Girona, Flamengo, Santos Laguna, Portimonense, Lommel and Kortrijk.

He has been capped eight times by Colombia but has not been selected for a national squad since 2016.

Born in Medellín, Moreno joined Atlético Nacional's youth setup in 2010, aged 14. On 23 July 2014, he made his first team debut, coming on as a second-half substitute for Rodin Quiñónes in a 3–1 Copa Colombia away win against Rionegro Águilas.

Moreno made his Categoría Primera A debut on 15 October 2014, starting in a 2–1 loss at Deportivo Pasto. He scored his first professional goal on 10 September of the following year, netting the second in a 3–0 home win against Deportivo Cali.

On 17 October 2015, Moreno scored a brace in a 4–0 away routing of Atlético Junior. He also started in the season's final against the same team, scoring from 30 seconds and helping his team to win its first title of the year; it was also the fastest goal of the club's history.

On 6 August 2016, Moreno signed for Manchester City for £4.75 million and was immediately loaned out to Deportivo de La Coruña, in a season-long deal.

Moreno made his debut for Deportivo on 11 September, in a 1–0 loss to Athletic Bilbao.
