Ione /aɪˈoʊn/ is a town in Pend Oreille County, Washington, United States.

[6] The timber industry played a major role in Ione's history.

In the early 1900's, Frederick A. Blackwell's Panhandle Lumber Company opened the inland northwest's first all-electric sawmill in Ione.

[5] Ione is situated on the west bank of the Pend Oreille River as it flows north towards Canada.

Ione Bridge, on the southern edge of town, is the only road crossing of the Pend Oreille between Metaline Falls to the north and Usk to the south.

Being located in the Selkirk Mountains, the area immediately surrounding Ione is of high topographic relief.

The town itself is on a relatively flat area along the river at an elevation of 2,090 feet above sea level, but the mountains rise dramatically both sides of the Pend Oreille.

[7] Cement Mountain, with its peak roughly a mile immediately north of town, rises to 3,003 feet.

[8] Molybdenite Mountain, across the river from Ione, rises even higher to 6,788 feet.
