La Usurpadora (English: The Usurper; international title: Deceptions) is a Mexican romantic drama telenovela produced by Salvador Mejia Alejandre and originally broadcast on Canal de las Estrellas from February 9 to July 24, 1998.

It starred Gabriela Spanic and Fernando Colunga, and was based on La intrusa, a novela originally broadcast in Venezuela which was itself a remake of Radio Caracas Televisión's 1971 telenovela La Usurpadora, which starred Marina Baura and Raúl Amundaray. This was one of the last telenovelas to feature Libertad Lamarque, who here portrayed the character of Abuela Piedad Bracho, until Carita de ángel.

Inspired by the book The Scapegoat, it revolves around a pair of twin sisters who were separated when they were young, and as adults the good sister is forced to act as a "replacement" for her wealthy twin who wants to temporarily leave her husband and his family to enjoy a life of luxury with multiple lovers. The telenovela had huge success in Mexico with ratings of 38.4 and has been exported and dubbed in various languages across the world.

It was the first on-screen collaboration between Colunga and Spanic, who both later worked in Soy tu Dueña.
