McDonogh 19 Elementary School is an American elementary school located at 5909 St. Claude Avenue in the Lower Ninth Ward of New Orleans, Louisiana. Along with William Frantz Elementary School, it was involved in the New Orleans school desegregation crisis during the early 1960s.

The school was built in 1929. It was funded by John McDonogh through the McDonogh Fund which built schools in New Orleans and in Baltimore, Maryland. It was designed in Italian Renaissance Revival style by the New Orleans Parish School Board's architect E.A. Christy.

It was an all-white school, integrated in the fall of 1960 by three young black girls, Leona Tate, Tessie Prevost, and Gail Etienne, known as the McDonogh Three.

It was listed on the National Register of Historic Places in 2016.

In 2021, the building was purchased by Leona Tate and her foundation, to be transformed into a museum chronicling Civil Rights history with the help of Xavier University's Investigative Stories Program.
