Mus mayori is a species of rodent in the genus Mus, the mice. Its common names include Mayor's mouse, highland rat, and spiny mouse.Wijesinghe, M. R. Predicting effects of rainforest fragmentation from live trapping studies of small mammals in Sri Lanka. Journal of Threatened Taxa 4(6): 2629-2636. It is endemic to Sri Lanka.
This mouse lives in tropical and subtropical forest types and wet grassland habitat. It is fossorial, seeking shelter by digging burrows. It is nocturnal.
This species is widespread in parts of Sri Lanka but it faces a number of threats, including deforestation and domestic cats.
There are two subspecies, M. m. mayori and M. m. pococki. A recent study catalogued the parasites associated with subspecies pococki: a mite of genus Echinolaelaps, a tick of genus Ixodes, and the sucking louse Polyplax spinulosa.Ratnaweera, P. B., et al. (2010). Parasitic associations of a threatened Sri Lankan rainforest rodent, Mus mayor pococki (Rodentia: Muridae). Journal of Threatened Taxa, 2(6), 901-907. A new species of pseudoscorpion was found on the mouse, described, and named Megachernes kanneliyensis.Harvey, M. S., et al. (2012).

Journal of Natural History, 46(41-42), 2519-2535. The mouse also carries the native Sri Lankan flea Stivalius phoberus.Yathramullage, S., Meegaskumbura, M., and Meegaskumbura, S. (2014).
