沟酸浆属（学名：Mimulus）是透骨草科下的一个属，为草本或灌木植物。该属共有约150种，分布于全球。

Mimulus /ˈmɪmjuːləs/ is a diverse plant genus, the monkey-flowers and musk-flowers. The about 150 species are currently placed in the family Phrymaceae. The genus had traditionally been placed in Scrophulariaceae. The removal of Mimulus from that family has been supported by studies of chloroplast DNA first published in the mid-1990s. Multiple studies of chloroplast DNA and two regions of nuclear rDNA suggest that the genera Phryma, Berendtiella, Hemichaena, Leucocarpus, Microcarpeae, Peplidium, Glossostigma, and Elacholoma are all derived from within Mimulus and would need to be rearranged.
