Alexandria Ocasio-Cortez (often referred to as AOC) has deep roots in Puerto Rican heritage, shaped by generations of migration, resilience, and cultural pride.
Her ancestry is a reflection of the broader Puerto Rican experience, encompassing Spanish, Indigenous Taíno, and African influences, which have historically defined the island’s diverse population.
Alexandria Ocasio-Cortez was born on October 13, 1989, in the Bronx, New York City. Her parents, Blanca Ocasio-Cortez and Sergio Ocasio, were both of Puerto Rican descent, making her a second-generation Puerto Rican American.
While she was born and raised in the U.S., her family maintained a strong connection to Puerto Rico, shaping her identity and cultural awareness.

Puerto Rico itself has a complex ethnic and historical background. As a former Spanish colony, the island’s people are a mix of Indigenous Taíno, Spanish European, and African ancestry—three groups that intermingled over centuries due to colonization, slavery, and migration. AOC’s lineage, like that of many Puerto Ricans, is likely to reflect this multi-ethnic heritage.
Alexandria Ocasio-Cortez’s Father’s Side: The Ocasio Lineage
Her father, Sergio Ocasio, was born in the Bronx but had roots tracing back to Puerto Rico. He was an architect who passed away from lung cancer in 2008 when AOC was just 19 years old. The Ocasio name is of Spanish origin, and it is common among Puerto Ricans, often linked to families with Iberian (Spanish) ancestry.
Sergio Ocasio’s family likely migrated from Puerto Rico to New York during the mid-20th century, a period when many Puerto Ricans moved to the mainland U.S. in search of better economic opportunities, especially in industrial cities like New York.
This wave of migration was part of a broader trend known as the Great Migration of Puerto Ricans during and after World War II, facilitated by Puerto Rico’s status as a U.S. territory.
Alexandria Ocasio-Cortez’s Mother’s Side: The Ocasio-Cortez Name and Puerto Rican Roots
AOC’s mother, Blanca Ocasio-Cortez, was born and raised in Puerto Rico. Unlike her husband’s Bronx upbringing, Blanca had firsthand experience of life on the island. Growing up in Puerto Rico, she was immersed in its culture, language, and history before eventually moving to the U.S.
The surname “Cortez” suggests Spanish heritage, as it is a common surname of Iberian origin. It is possible that her family lineage includes Spanish settlers who arrived in Puerto Rico centuries ago, along with Indigenous Taíno and African ancestors, a blend that characterizes the Puerto Rican identity.

Blanca later moved to the mainland U.S., where she met and married Sergio. After his passing, she worked as a house cleaner and bus driver to support Alexandria and her younger brother, Gabriel Ocasio-Cortez.
Puerto Rican Heritage and Cultural Identity
Puerto Rico’s history is shaped by Spanish colonization, the transatlantic slave trade, and Indigenous Taíno resistance. AOC’s ancestry likely reflects this diverse heritage.
The Spanish colonists arrived in Puerto Rico in the late 15th century, intermarrying with the Indigenous Taíno people, who were the island’s original inhabitants. African slaves were later brought to the island to work on plantations, further enriching Puerto Rico’s racial and cultural identity.
AOC has often spoken about her Puerto Rican heritage with pride, emphasizing the struggles and contributions of the Puerto Rican community in the U.S. She has also been vocal about Puerto Rico’s political status as a U.S. territory and its historical relationship with the U.S. government.
Ethnic and Cultural Roots
Alexandria Ocasio-Cortez’s ethnic and cultural roots are deeply tied to Puerto Rico’s history and its people’s migration to the United States. With parents of Puerto Rican descent—her mother born on the island and her father raised in the Bronx—AOC embodies the experience of many Puerto Ricans who have navigated the complexities of identity, heritage, and American life.
Her background reflects the resilience and strength of the Puerto Rican diaspora, a narrative that continues to shape her political vision and personal journey.
