Rogaland [ˈruːɡɑˈlɑn] (listen) is a county in Western Norway, bordering Hordaland, Telemark, Aust-Agder, and Vest-Agder counties. Rogaland is the center of the Norwegian petroleum industry. In 2016, Rogaland had an unemployment rate of 4.9%, one of the highest in Norway. In 2015, Rogaland had a fertility rate of 1.78 children per woman, which is the highest in the country.

Rogaland is the Old Norse name of the region which was revived in modern times. During Denmark's rule of Norway until the year 1919, the county was named Stavanger amt, after the large city of Stavanger. The first element is the plural genitive case of rygir which is probably referring to the name of an old Germanic tribe (see Rugians). The last element is land which means "land" or "region". In Old Norse times, the region was called Rygjafylki.

The coat-of-arms is from modern times; they were granted on 11 January 1974. The arms are blue with a white or silver pointed cross in the centre. The cross is based on the old stone cross in Sola, the oldest national monument in Norway. It was erected in memory of Erling Skjalgsson after his death in 1028. This type of cross was very common in medieval Norway.
