Gottfried Ludwig Theobald (21 December 1810 in Allendorf – 15 September 1869 in Chur) was a German-Swiss geologist and cartographer.

He studied theology at the universities of Marburg and Halle, then served as a curate in Hanau.

From 1854 up until his death, he taught classes in sciences at the cantonal school in Chur.

He also provided geological descriptions of Swiss mineral springs; such as those at Tarasp, St. Moritz, Alvaneu, Rothenbrunnen and Passugg, as well as descriptions of the springs at Bormio in Italy.
