Alexandria Ocasio-Cortez, who was raised as Catholic, claims she actually has Jewish roots that span back 500 years to the Spanish Inquisition.

The congresswoman-elect made the ancestral connection for the first time during a Hanukkah celebration Sunday in Queens — without offering any evidence.

“A very, very long time ago, generations and generations ago, my family consisted of Sephardic Jews,” the 29-year-old Democrat told the audience at the Jackson Heights Jewish Center.

“The story goes, during the Spanish Inquisition, so many people were forced to convert on the exterior to Catholicism, but on the interior continued to practice their faith … And some of those people landed in Puerto Rico, and some of those people decided to flee up in into the mountains.”

In a series of Twitter posts on Monday, the socialist Democrat said Puerto Ricans in general are a mix of cultures that include “Jewish refugees and likely others.”

“Before everyone jumps on me – yes, culture isn’t DNA,” she tweeted.

“But to be Puerto Rican is to be the descendant of: African Moors & slaves, Taino Indians, Spanish colonizers, Jewish refugees, and likely others. We are all of these things and something else all at once – we are Boricua,” she wrote, referring to the colloquial term for Puerto Ricans.

She didn’t offer any specifics about her own family history.

Ocasio-Cortez’s mom was born in Puerto Rico and her dad in The Bronx.

Her family lived in The Bronx’s Parkchester section and moved to Westchester so Ocasio-Cortez could enroll in better schools.
