Marco Tobón Mejía (1876-1933) was a Colombian sculptor, draughtsman, and painter. He lived in France for almost all his career, where he met and formed relationships with several prominent artists, including Auguste Rodin, Aristide Maillol, and Antoine Bourdelle. He worked mostly within neoclassic and art nouveau styles, and is known especially for his sculptures in bronze, electroplate, and pewter. Several of his pieces can be found in the Colombian National Museum.
His marble statues Poetry and The Silence are dedicated to the Colombian poet José Asunción Silva.
