Port Hadlock-Irondale is a census-designated place (CDP) in Jefferson County, Washington, United States.

About 1,200 tons of pig iron was produced during its first year of operation, with ore obtained from Chimacum Valley.

[5] The initial hope was for Irondale to become a major iron and steel producer for the western United States.

After only two years of production, Irondale had several bars, boarding facilities for both men and horses, and homes and accommodations for over 200 workers.

He contracted with the Washington Mill Company to build a sawmill on a spit of land at the south end of Port Townsend Bay, on a low bank, but deep enough waters for tall ships to moor.

On the waterfront near the mill were a general store, post office, barber shop, livery stable, laundry, two hotels and two saloons.

The saloons were frequented by sailors from all over the world as well as local mill workers, longshoremen, and loggers.

The alcohol plant was renovated into a resort, which included an inn, restaurant, marina and art gallery.

Subsequent industries have included a boat building yard and a clam cannery.

In 1946 Melvin Kivley established the first businesses at the Hadlock intersection - a secondhand store and a Signal Service Station.

The CDP includes the communities of Port Hadlock and Irondale, plus part of Chimacum, all of which form what is locally known as the "tri-area".
