Oakdale is a town located along the Emory River in Morgan County, Tennessee, United States.

In the 1880s, the Cincinnati Southern Railway, which connected Chattanooga and Cincinnati, was built through the area, intersecting the vast system of the East Tennessee, Virginia and Georgia Railroad (later the Southern Railway) at Emory Gap near Harriman.

[5] In 1905, this hotel was converted into one of the nation's largest YMCA facilities,[9] with 1,500 beds and its own library and clinic.

[5] The advent of diesel locomotives, which could handle the steep grades without modifications, eliminated the need for the Oakdale railyard, and the town declined in the mid-20th century.

The western side is located along a slope that descends from State Route 299 to a flood plain along the river, and includes the town hall, fire department, and several houses.

The eastern side is located in a hollow just north of SR 299, and includes a post office, park, and several more houses.

SR 328, which lies east of the river, connects the town with Harriman to the south and US 27 to the north.

SR 299, which crosses the river, connects the town to I-40 and the Westel area in Cumberland County to the southwest.
