Pontymister (Welsh:Pont-y-meistr) is a small village in Caerphilly county borough in Wales.
Originally a farm called Tŷ Isaf, the village came about as a need for housing for the local steel mill and chemical works workforces.
From the late 1800s there were a number of heavy industries, (steel and chemical), based alongside the River Ebbw.
The name Pontymister is said to have come about as the staff were paid from an office built alongside the bridge that connected Tŷ Isaf to Ochrwyth.
