Ernst Georg Pritzel (15 May 1875 – 6 April 1946) was a German botanist.
He contributed works on Lycopodiaceae, Psilotaceae and Pittosporaceae to Engler & Prantl’s "Die Natürlichen Pflanzenfamilien".
[1] In 1900–02, with Ludwig Diels, he collected plants in South Africa, Australia and New Zealand.
They published the results of their expedition (a collection of 5700 species) in the Botanische Jahrbücher in 1904–05.
[2] Pritzel issued and distributed the exsiccata-like specimen series Plantae Australiae occidentalis 1901–1902 editae.
