Eagle Mills Township is a rural, non-functioning subdivision of Iredell County, North Carolina, United States. By the requirements of the North Carolina Constitution of 1868, the counties were divided into townships, which included Eagle Mills. Eagle Mills Township was named for the town of Eagle Mills (also referred to as Eagle City for a time), which was established by Andrew Baggerly on Hunting Creek in 1848.

In 1846, Andrew Baggerly bought land on Hunting Creek in north Iredell County. He constructed a dam and built a sawmill and grist mill, and started construction of a factory building. He put an ad in Salisbury's Carolina Watchman newspaper that read, "the most valuable water power in the Southern Country … situated on Hunting Creek in Iredell County, twenty-eight miles west of Salisbury … [on] a never-failing stream, … remarkable for its purity, … [and] adapted to the manufacture of paper, to calico printing, to bleaching etc." By 1852, William I. Colvert was operating a knitting mill in Eagle Mills. It had 700 spindles and 12 looms and employed an overseer and 22 workers, 20 of whom were women. In 1854, Baggerly was calling the site Eagle City. Baggerly was forced to sell his interests in Eagle Mills to William Colvert during the Panic of 1857. “According to tradition there was a tobacco factory, hotel, oil mill, and general store at Eagle Mills in addition to the grist mill and cotton factory. A number of homes stood in the horseshoe bend above the mills and a church was eventually constructed on the edge of the settlement.” During the Civil War, Stoneman's raiders burned Eagle Mills to the ground. After the war, the mills were rebuilt but Eagle Mills never returned to its former splendor. A fire in April 1894 destroyed the rebuilt mills and only the foundations remained. Some gravestones still remain.

Andrew Baggerly was the post master when the Eagle Mills post office was first established on August 3, 1848. This post office continued until September 29, 1894 when the name was changed to Eagle post office with Arthur L. Stimson as post master. The Eagle post office continued until November 15, 1907. There are currently no post offices in Eagle Mills Township. The Harmony post office is used.
