Mariana Duque Mariño (Spanish pronunciation: [maˈɾjana ˈðuke maˈriɲo]; born 12 August 1989) is a Colombian former tennis player. Having turned professional in 2005, she reached a career-high singles ranking of world No. 66 in October 2015.

Duque debuted on the ITF Junior Circuit in 2004. As a junior, she reached the final of the girls' singles tournament at the 2007 French Open. She defeated the tenth-seeded Ksenia Pervak in the first round, and ousted juniors' world No. 1, Anastasia Pavlyuchenkova, in the semifinals. Duque lost in the final to Alizé Cornet in three sets. She had some setbacks during the tournament, due to losing her tennis rackets at the airport. Without money to buy replacements, she had to play with borrowed rackets.

She won her first professional tournament in May 2006, in Mazatlán, Mexico. Her biggest win in senior competition is defeating 26th seed Anna Chakvetadze in the opening round of the 2009 French Open, in three sets.
