Carl Theodor Schulz (5 April 1835 – 16 August 1914) was a Norwegian gardener.

He was born in Berlin, Germany, the son of Christian Schulz, a tailor.^[1] In the 1850s, the young Schulz worked at some market gardens in Berlin and its edge city Potsdam; he was employed at a botanical garden in Hamburg in the subsequent decade.^[2] In March 1865, after five years of work in Hamburg, he was hired at the University Botanical Garden in Oslo.^[3] He was appointed head gardener in 1893, succeeding the deceased Nils Green. Schulz stayed in that position until his death.^[1] In 1895 he released the work Om botaniske haver.^[3]

Schulz was a founding member of the Christiania Gardener Association and the Norwegian Horticulture Society; he was the first chairman of the former, and vice-chairman of the latter organisation.^[2][4] From 1892 to 1902, he sat on the board of the Horticulture Society.^[1][2]

The person who recruited Schulz to Norway was Frederik Schübeler. Schulz married an adopted daughter of Schübeler's, Ingeborg Strengberg (1853–1918), in February 1875 in Østre Aker.^[1]
