Samu Pecz (born as Petz, Pest, 1 March 1854 – Budapest, 1 September 1922) was a Hungarian architect and academic.
Pecz studied at a number of universities both at home and abroad in Stuttgart, later at the Vienna Academy of Fine Arts under the Danish architect Theophil Hansen, the builder of the Austrian Parliament Building, Musikverein, and Stock Exchange buildings in Vienna.
After returning to Budapest he worked with Frigyes Schulek on the Matthias Church in Buda and later in the offices of Alajos Hauszmann. At this time he familiarised himself with Gothic architecture, particularly in church design. Later, Pecz worked in the technical university under Schulek and Imre Steindl and became a lecturer is 1887. He was 34 years old when he became the dean of the building faculty which he continued to be until his death. He designed numerous buildings in the historicist tradition, often employing Zsolnay tiles to rich effect.
