Viktor Holtz (3 May 1846 – 3 September 1919) was a German educator and a pioneer of German-Japanese academic and cultural relations.
Holtz was born in Stolberg, Kingdom of Prussia, and studied, from 1865 to 1867, at the Royal Catholic Teacher's Academy in Kempen.
Together with the more famous military surgeons Theodor Eduard Hoffmann and Leopold Benjamin Müller, he belonged to the first group of Germans whom Prussia dispatched to modernize and westernize schools of higher education in Japan.
Therefore, inconsistent educational planning terminated the pioneer experiment of a German school in Japan without direct lasting effects.
On October 1, 1874, he returned to Boppard and took over after the appointment of J. Hoffmann to the district school inspector teaching in mathematics, German and piano and was transferred in 1877 to Prüm (near Koblenz), in 1889 to Schrimm and in 1902 to Poznań, Poland where he died in 1919.
