Johann Heinrich Linck the Younger (5 January 1735 – 23 May 1807) was a German pharmacist, naturalist and collector. He came to own the Linck natural history cabinet founded by his grandfather who also owned the Zum Goldenen Löwen (Lion pharmacy) in Leipzig. His father Johann Heinrich Linck (the elder) extended the collections. He documented the collections of the Linck Museum in three volumes.
