Blaenavon Ironworks, officially spelled Blaenafon Ironworks since 2024, is a former industrial site which is now a museum in Blaenavon, Wales. The ironworks was of crucial importance in the development of the ability to use cheap, low quality, high sulphur iron ores worldwide. It was the site of the experiments by Sidney Gilchrist Thomas and his cousin Percy Gilchrist that led to "the basic steel process" or "Gilchrist–Thomas process".

The National Museum of Wales has turned this former coal mine into a look back at what mining life was like in days gone by. The highlight of the trip is an underground tour of the mine itself, led by a retired Welsh miner.
