Johann Salomo Christoph Schweigger (8 April 1779 – 6 September 1857) was a German chemist, physicist, and professor of mathematics born in Erlangen.

In 1811, he proposed the name "Chlorine" for the substance discovered in 1774 by Carl Wilhelm Scheele and properly identified by Humphry Davy as an element in 1810.

In 1820 he built the first sensitive galvanometer, naming it after Luigi Galvani. He created this instrument, acceptable for actual measurement as well as detection of small amounts of electric current, by wrapping a coil of wire around a graduated compass.

He is the father of Karl Ernst Theodor Schweigger and adopted one of his students Franz Wilhelm Schweigger-Seidel as his own son.
