John Austin (1790-1859) was a noted British jurist and published extensively concerning the philosophy of law and jurisprudence.

Austin served with the British Army in Sicily and Malta, but sold his officer's commission to study law. He became a member of the Bar during 1818.

In 1820, Austin married Sarah Austin (1793–1867), born Sarah Taylor, an English editor & linguist.

He discontinued his law practice soon after, devoted himself to the study of law as a science, and became Professor of Jurisprudence in the University of London (now University College London) 1826-32. Thereafter he served on various Royal Commissions.

His publications had a profound influence on English jurisprudence. They include The Province of Jurisprudence Determined (1832), and Lectures on Jurisprudence.
