Thomas's vlei rat (Otomys thomasi) is a species of rodent in the family Muridae. It is endemic to Kenya's high plateau mountains of the Rift Valley.[1][3]


Osgood (1910) initially described this species as Otomys thomasi.[2] In 2006, it would be included under Otomys orestes (afroalpine vlei rat) by Carleton & Byrne.[1] Taylor et al. (2011) reviewed the genus Otomys and moved Otomys thomasi back to species status.[4][1]


It is known from less than 10 locations in Kenya and isn't recorded in protected areas, hence the assessment of the species as "Vulnerable" by the IUCN.[1]
