María Guadalupe Loaeza Tovar (born in 1946) is a contemporary Mexican writer, author of many books including Las Niñas Bien, Las Reinas de Polanco, Debo, Luego Sufro and Compro, Luego Existo, in which she ironizes about the Mexican upper class. A participant in Elena Poniatowska's writing workshops in the mid-1980s, she has transformed her success as a chronicler, observer, and critic of the Mexican bourgeoisie and the post-1985 democratization of Mexico into a successful career. Known for her trademark pearl necklace (a family heirloom) and for her francophile tendencies, she has become an influential cultural figure. Some of her books are compilations of her articles published in newspapers such as Unomasuno and La Jornada. She was born in Mexico City. She had two children from her first marriage. In 2003, Guadalupe Loaeza received the distinction of Chevalier from the Légion d'Honneur of France.
As of 2008, Loaeza is a columnist for the Reforma newspaper and is married to Dr. Enrique Goldbard.
