Mette Magrete Tvistman (1741, Frørup – 9 February 1827, Snejbjerg) was a Danish artist (clockmaker). She is known in Danish history as the first female clockmaker in her country. Mette Magrete Tvistman was the daughter of the blacksmith and clockmaker Christen Jensen (1703–1781) and Maren Nielsdatter (1700–1791). She married the clockmaker Johan Ahlert Tvistman (1721–1769) in 1760, and had two children. In 1771, she married the farmer Christen Jensen, and had a daughter, but quickly divorced him. She was engaged to a son of the influential cleric Ude Haahr of Holstebro in 1788, but broke the engagement, which was regarded a scandal.
