Jean Pütz (born 21 September 1936) is a German science journalist and TV host.

He originally took an education as an electrician before completing his Abitur, after which he studied physics, mathematics, sociology, and national economy.

He is mainly known for his show Hobbythek [de] which ran for nearly 30 years, from 1974 up to 2004, on the channels WDR and NDR Fernsehen, where he explained scientific phenomena with an emphasis upon do it yourself, environmentally-friendly homemade solutions for everyday health and household problems.

Beside the Hobbythek books, Pütz also authored more than 20 other guidebooks dedicated to health, food, gardening, popular science, nature, and do-it-yourself hobbies.

The end of Hobbythek in 2004 came unconsensually, when Pütz's show was cancelled against his own intentions by his former protégé Ranga Yogeshwar, now head of WDR's science department.
