Paul Walden ( _lv. Pauls Valdens; 1863 – 1957) was a Latvian-German chemist. He was born in the parish of Rozula near Cēsis in Latvia and initially studied at the Riga Polytechnicum and St. Petersburg before receiving his doctorate at the University of Leipzig in 1891 with Wilhelm Ostwald.

Walden left Latvia after the Russian Revolution and accepted positions in Germany. The Walden inversion is named after him. Walden also invented ethylammonium nitrate Ref|1 as the first example of an ionic liquid. Walden is also known for his 1949 book, "History of Chemistry", an excellent synthesis of contemporary historical research in the field.
