Krisztina Téri Iskola, Catholic school in Krisztinaváros district, Budapest, Hungary.

Krisztina Téri Iskola is a school building at Krisztina tér in Budapest's Krisztinaváros district, erected in 1883 on a plot enlarged toward the church. Its classrooms were arranged along corridors, with a light-green oil baseboard 1.5 metres high that pupils scratched with holes, and a vertically sliding blackboard on a 15–20 cm teacher's platform. Since 1997 it has housed the Szent Gellért Catholic Primary School and Grammar School.

The school was founded in 1787 and initially held classes in a pub building before relocating to its current site in 1883. This move happened during a period of major educational expansion in Budapest as the city modernized.

The building has housed the Szent Gellért Catholic Primary School and Secondary Grammar School since 1997, when the state school on Krisztina Square closed. The square and the school keep the Krisztinaváros name, and the building faces the church towards which its plot was enlarged in 1883.

The school sits in a central location at Krisztina Square and is easy to find and view from the street. Keep in mind that this is an active school building reserved for students and staff during school hours, so access may be limited.

The Tabán school in Czakó Street was destroyed by a bomb in January 1945, and its pupils then attended lessons in the Krisztina Square building until Naphegy got its own school in 1958. In 1976 the music video for István Bergendy and Ferenc Demjén's song "Iskolatáska" was filmed here.
