Valley Mills is a city in Bosque and McLennan counties in central Texas, United States.

The McLennan County portion of Valley Mills is part of the Waco Metropolitan Statistical Area.

In 1881, the Gulf, Colorado and Santa Fe Railway (GC&SF) laid tracks a mile south of the community, across the Bosque River.

By 1900, however, the railroad and the nearby Chisholm Trail had made Valley Mills a prosperous retail and trading center for Bosque and McLennan counties.

During the next three decades Valley Mills maintained its position as a leading retail market and shipping point for Bosque and McLennan counties.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters.
