Lazzaro Uzielli (4 February 1861 − 8 October 1943) was an Italian pianist and music educator.

Born in Florence to a banking family, Uzielli studied in his home town with Luigi Vannuccini und Giuseppe Buonamici, then with Ernst Rudorff in Berlin, and with Clara Schumann and Joachim Raff at Dr. Hoch's Konservatorium in Frankfurt.

From 1883 to 1907 he worked as a teacher at Dr. Hoch's, and then followed a call to the Hochschule für Musik Köln.

He was the pianist of the 'Cologne Trio,' which also included Bram Eldering, violinist, and the cellist Friedrich_Grützmacher, and after the latter's death, Emanuel Feuermann.
