The Church of St. Jerome is a Roman Catholic parish church under the authority of the Roman Catholic Archdiocese of New York, located at 230 Alexander Avenue, Mott Haven, Bronx, New York City.

As the Puerto Ricans moved on, Mexican immigrants form the largest population in the community with small numbers of Dominicans and West Africans.

For several years past the present church, which is very old has been inadequate to meet the demands of the growing congregation.

[9] In 1898, it was reported that "the erection of the new church will necessitate the moving of the Academy of the Ursuline Sisters, a three-story and basement brick structure now directly in the rear of the present church> it will be moved further east on 137th Street, and additions will be made to it.

Between the Ursuline convent, which faced E. 137th St., and the boys' school, a secluded garden was created for the nuns to recite the Office as they walked in a circle.
