Johannes (Hans) Gottfried Hallier (6 July 1868 – 10 March 1932) was a German botanist born in Jena.
He studied botany and zoology at the University of Jena under Christian Ernst Stahl (1848–1919) and Ernst Haeckel (1834–1919), and continued his studies at the Ludwig-Maximilians-Universität München under Ludwig Radlkofer (1829–1927) and Richard Hertwig (1850–1937). From 1893 until 1897, he was based at the Buitenzorg Botanical Garden in Java.
In 1894, Hallier became the second European to climb Mount Kelam (after a certain Dr. Gürtler) and the first to collect specimens of the pitcher plant Nepenthes clipeata.McPherson S (2009).
