Catharina Bröms (1665-1735), was a Swedish ironmaster. She was the owner of the Wij iron works at Ockelbo between 1686 (formally 1708) and 1735. She founded and acquired additional iron works and eventually owned the larger part of Ockelbo and its parish. Bröms was a successful industrialist who managed to avoid the economic depression in the iron industry during the Great Northern War and became known as "Her Grace at Wij".
