Inés María Mendoza Rivera de Muñoz Marín (January 10, 1908, in Naguabo, Puerto Rico – August 13, 1990 in San Juan), was a former First Lady of Puerto Rico, teacher, writer and socialite. She was the second wife of Governor Luis Muñoz Marín.
Mendoza was an accomplished student in her native Naguabo. She was accepted into the University of Puerto Rico and later to Columbia University in New York, where she graduated in 1931. She was married to painter Rafael Palacios from 1931 to 1935 and during this marriage they had two children: Carmen Palacios Mendoza and Rafael Palacios Mendoza.
She returned to Puerto Rico to begin her career as a teacher, writer and newspaper columnist. In 1935, she would meet Muñoz Marín during one of his campaign stops in Naguabo. Although he was married to American writer Muna Lee, Muñoz Marín would move in with her a few years afterwards. They were married on November 16, 1946, a day after his divorce from Muna Lee was finalized. Their marriage produced two daughters, Viviana Muñoz Mendoza and Victoria Muñoz Mendoza.
In 1948, Luis Muñoz Marín was elected Governor of Puerto Rico. Mendoza lived at "La Fortaleza", the Governor's mansion, for sixteen years. As First Lady, she showed interest in Puerto Rico's ecology and public education system. After her husband retired as Governor in January 1964, she returned to private life.
Luis Muñoz Marín died on April 30, 1980. Doña Inés, as she was known to close friends and family, died a decade after his death on August 13, 1990. A few years after her death, Mendoza's daughter, Victoria, attempted an unsuccessful campaign as the candidate for the Popular Democratic Party candidate for the island's governorship. She was defeated by Pedro Rosselló, the candidate for the New Progressive Party. Had she been elected, she would have become the island's first female governor. That honor would later go to Sila María Calderón when she was elected as the island's first female governor in 2001.
