The Battle of Tarqui, also known as the Battle of Portete de Tarqui, took place on 27 February 1829 at Tarqui, near Cuenca, today part of Ecuador. It was fought between troops from Gran Colombia, commanded by Antonio José de Sucre, and Peruvian troops under José de La Mar. Although the Colombian troops achieved victory over the Peruvian vanguard, destroying it and forcing the rest of their forces to withdraw, they suffered heavy losses in their cavalry with the Peruvian charge, which made it difficult to continue the campaign and caused the stabilization of the front.

The Presidential Escort Group "Granaderos de Tarqui" is the President of Ecuador's honour guard service regiment, which protects the Carondelet Palace in Quito. Granaderos de Tarqui, means Tarqui Grenadiers in Spanish.
