Conrad Wilhelm Hase (2 October 1818, Einbeck – 28 March 1902, Hanover) was a German architect and Professor.
On the advice of one of his teachers, Ernst Ebeling, he began an apprenticeship as a bricklayer with the builder, Christoph August Gersting.
A scholarship from the city of Einbeck enabled him to complete his studies at the Academy of Fine Arts, Munich.
The following year, he became a teacher at the Technical University of Hanover, and was one of the founders of the Architects and Engineers' Association [de].
His students there included Edwin Oppler, Heinrich Gerber, Wilhelm Walter, Georg Kegel and Richard Kampf.
