Conrad Moench (sometimes written Konrad Mönch; 15 August 1744 – 6 January 1805) was a German botanist, professor of botany at Marburg University from 1786 until his death.

He wrote 'Methodus Plantas horti botanici et agri Marburgensis' in 1794, an arranged account of plants in the fields and gardens of Marburg.

In 1802 he named the plant Gillenia trifoliata in a supplement to a local flora of the city of Marburg.
