Johan Christian Fabricius (January 7, 1745 – March 3, 1808) was a Danish entomologist and economist.

Fabricius was born at Tønder in the duchy of Schleswig. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoega to Uppsala, where he studied under Carl von Linné for two years.

Fabricius worked primarily with arthropods and was a specialist on insects, classifying many spiders including the black widow. He was professor of natural history, economy and finance at the University of Kiel from 1775. He was a regular visitor to London where he studied many collections.

His works on insects included:

• Systema Entomologiae (1775),
• Genera Insectorum (1776),

• Mantissa Insectorum (1787), and his main work,
• Entomologicae Systematica, revised and corrected, 4 volumes, (1792-1794); followed by
• Supplementum Entomologiae Systematicae (1798).
