Dufour school house, School building in Neustadt Nord, Biel, Switzerland.

Dufour school house is an educational building in Biel's South New City area that provides instruction in German and French alongside specialized support services. It features dedicated spaces for psychomotor development and speech therapy to meet the diverse learning needs of its students.

The Johanniterorden founded a monastery with its church here in 1454/55, after Komtur Heinrich Staler negotiated with Biel, which waived dues and helped demolish six houses. When the order gave up the site, the city moved its hospital (founded 1445) into the rooms in 1559 and demolished the monastery church. From 1818 the former monastery housed Biel's bilingual Gymnasium, opened on 15 September 1817.

The school's name recalls General Guillaume-Henri Dufour, and its bilingual mandate dates to the 1815 act joining Biel to Bern, which required a French-language gymnasium where German speakers learned French and vice versa. The 1817 opening took place in the Stadtkirche, with rector Appenzeller calling for a humanist school on the German model.

The main entrances of both schoolhouses face General-Dufour-Strasse, and the schoolyard opens onto Ernst-Schüler-Strasse. The complex fills the block bounded by General-Dufour-Strasse, Neumarktstrasse, Ernst-Schüler-Strasse and Gartenstrasse, south of Biel's old town. The city library stands on the neighbouring plot, and the two buildings are linked by an intermediate wing.

The half-round Klosterturm, a defensive tower that reinforced the wall from the Nidautor to the Rote Turm, was demolished when the west school was built in 1862; its stones were reused in 1870 for a tower at the Villa Elfenau in the Pasquart. The Rote Turm, used as library and prison, was pulled down in 1871.
