Walhalla is a city in the foothills of the Blue Ridge Mountains in Oconee County, South Carolina, United States.

[5] While its population was 4,072 as of the 2020 census, "Walhalla" is used both colloquially and practically to refer to a larger area than is within city limits, often being expanded to the whole 29691 zip code.

The German Colonization Society of Charleston was founded in 1848 to aid a wave of immigrants from the failures of the German revolutions of 1848-1849 and settle them in The Upstate; in the aftermath, numerous liberal merchants and farmers immigrated to the United States.

Society trustees including General John A. Wagener, Claus Bullwinkel, John C. Henckel, Jacob Schroder, and Christopher F. Seeba bought 17,859 acres (72.27 km2) of land for $27,000 from Reverend Joseph Grisham of West Union in the Pickens District on December 24, 1849, to support German settlement in this area.

[6] As mostly political refugees, the German colonists named their settlement Valhalla, in reference to the afterlife in Norse Mythology where warriors would go if selected to fight during Ragnarök.

[8] Ellicott Rock, Keil Farm, Oconee County Cage, Oconee Station and Richards House, St. John's Lutheran Church, Stumphouse Tunnel Complex, and Walhalla Graded School are natural formations and structures in Walhalla that have been listed on the National Register of Historic Places.

[11] The city developed in the northwestern part of the state near the Georgia and North Carolina borders.

The last nearby earthquake had its epicenter in Newry, South Carolina, and occurred at 7:42 am EDT on May 19, 1971.

As of the 2020 United States census, there were 4,072 people, 1,668 households, and 1,202 families residing in the city.

[18] Walhalla also hosts a Merchant Market every year, taking place shortly after the end of the Oktoberfest; it consists of many businesses selling food and gifts on Main Street.
