Rošpoh was attested in written sources in 1250 as am Rosspach (and as im Rospach in 1352, am Rosspach again in 1418, and am Rospach in 1445). The name is originally a hydronym that was transferred to the adjacent settlement. It is derived from the Middle High German compound Rosbach (from ros 'horse' + bach 'creek').[5] In the past the German name was Rossbach.[2]
