The community was named after Coleraine, Northern Ireland, the ancestral home of a share of the first settlers.[3] A post office called Colerain was established in 1825, and remained in operation until 1907.[4] Colerain was originally built up chiefly by Quakers from North Carolina and Virginia, who left those states due to their opposition to slavery.[5]
