Johann Gottlieb Hantzsch (19 March 1794 – 3 April 1848) was a German genre painter.
Initially he devoted himself to painting military motifs and Romantic depictions.
From 1827 Hantzsch painted mainly small motifs depicting domestic bourgeois life, some of which were etched by his friend Ludwig Richter.
Johann Gottlieb Hantzsch was married to Mathilde Kretzschmar (1805–1883).
After the death of his first wife, Johannes Richter married Hantzsch's second daughter, Julie Amalie.
