Mette Magrete Tvistman (1741, Frørup – 9 February 1827, Snejbjerg [da], Herning) was a Danish artist (clockmaker).
Mette Magrete Tvistman was the daughter of the blacksmith and clockmaker Christen Jensen (1703–1781) and Maren Nielsdatter (1700–1791).
In 1771, she married the farmer Christen Jensen, and had a daughter, but quickly divorced him.
During her stay at Holstebro, however, she seem to have been active more as the manager of the community poorhouse, which was housed at her farm, though she was officially listed as a clockmaker.
Her most productive period was that in Ølgod, when she owned one of the largest estates in the city, which she had made her workshop.
