Arnemetia was a goddess in Romano-British religion. Her shrine was at Aquae Arnemetiae ("waters of Arnemetia"), which is now Buxton in Derbyshire, England.^[1]

Arnemetia's name contains Celtic stems are ("against, beside") and nemeton ("sacred grove"). Her name is thus interpreted as "she who dwells in the sacred grove", suggesting Arnemetia may be a divine epithet rather than a name in its own right.
