Heinrich-von-Kleist-Realschule, Secondary school building in Böckingen district, Heilbronn, Germany.

The Heinrich-von-Kleist-Realschule is a Realschule at Kastanienweg 17 in the Kreuzgrund settlement on Böckingen land, the only school in that neighbourhood. The complex, built from 1970 and occupied on 14 September 1971, comprises the school building, a Pausenhalle, a Forum and a caretaker's flat; its facade design received a Hugo-Häring award in July 2011. It has been modernised inside and out since 2002.

The school was originally founded as Realschule West and relocated to its current location in 1971 from a former cigar factory building. This move marked an important turning point as the student body continued to grow.

The school is named after Heinrich von Kleist, the dramatist of "Käthchen von Heilbronn", a play set in Heilbronn; locals call him the "Käthchen-Dichter". The city council chose the name when the new building opened on 21 December 1971. A library opened in the ground floor in spring 1972, run jointly by the city library and the school with about 5,000 books, the first combined school and public library in the city district.

The building is located at Kastanienweg 17 in the Böckingen district and is easily accessible by public transit. Visitors should know this is an active school facility, so access restrictions and visiting hours apply outside regular class times.

In spring 1972 a library with around 5,000 books opened on the ground floor, run jointly by the Heilbronn city library and the school. It was the first combined school and public library in the city district, meant to serve the new Längelter and Schanz housing estates.
