Josef Velek ['jozɛf 'ʋɛlɛk], ing. (Master of Arts, Technology) (30 November 1939 – 30 April 1990) was a Czechoslovak (Czech) journalist, author and environmentalist.

Velek was born on 30 November 1939 in Klínec, Czech Republic.

He graduated in 1974, from the Faculty of Electrical Engineering of the Czech Technical University in Prague and in the same year co-founded the Brontosaurus Movement focused on nature conservation within the framework of the then official Socialist Youth Union.

He began to publish in the sixties, and from 1975 was a member of the editorial staff of the Mladý svět (Young world) weekly. He was considered a founder of the Czechoslovak environment-oriented journalism, and has repeatedly faced threats due to his critical texts.
