Varberg is a locality and the seat of Varberg Municipality, Halland County, Sweden with 35,782 inhabitants in 2019.

Varberg and all of Halland are well known for their "typical west coast" sandy beaches. In Varberg the coast changes from wide sandy beaches to rocky terrain that continues north into the Bohuslän archipelago and as far as the North Cape.

Varberg is located in a terrain of hills and plains. It is largely without trees and green areas, in its place are bald rocks and sand. The Swedish authoritative author and bishop Esaias Tegnér described it in 1826 as the least appealing place in Sweden, which has later been used in the marketing of Varberg. The sandy beaches are however very popular in the summer. Another main factor in Varberg is its natural surroundings. The landscape further inland has rolling hills with lakes and forests in contrast to the flatter coastal areas.

Near Varberg there is the VLF transmitter Grimeton, an interesting radio-technical facility and classified by UNESCO to be a World Cultural Heritage site. It can be visited during the summer. Bexell Cottage is also located in the area.
