Palm Valley is a ghost town, a formerly independent community on U.S. Route 79, now incorporated into Round Rock, in the county of Williamson, in the U.S. state of Texas.

The community was named for its founder, Swedish settler Anna Palm, a widow with six sons, who arrived in 1853.

The Palm Valley Lutheran Church was built in 1872 and doubled as a schoolhouse.

Two years later the home was also designated a Recorded Texas Historic Landmark and was open to the public as the Palm House Museum.

[4] By the beginning of the 21st century, Palm Valley Lutheran Church remained but the community had lost its distinct identity.
