Paula Arnold (Hebrew: ארנולד, פאולה; 1885–1968) was an Austrian-born Israeli journalist, botanist, and naturalist.

[1][2] Paula Kellner (later Arnold) was born in 1885 in Vienna, Austria, which was then the capital of the Austro-Hungarian Empire.

Her father, Leon Kellner, taught English literature at the University of Vienna and was one of the first to become a Zionist and member of Theodor Herzl's closest circle.

About this time, she began to lose her hearing, so she decided to abandon her dream of teaching English in Israel.

[1] Arnold's younger sister, Dora, was married for several years to the philosopher Walter Benjamin.
