Roinestad (Norwegian: Røynestad) is a hamlet of Kvinesdal Municipality in Agder county, Norway.
Røynestad is located on the river Kvina, about 7 kilometres (4.3 mi) north of the village of Liknes. It is contiguous with the village of Storekvina to the east. Røinestad is located 135 metres (443 ft) above sea level.
As typical in Norwegian tradition, persons who inhabited that area known as "Roinestad" in Kvinesdal adopted the name as their family (last) name. While Roinestad (sometimes spelled "Roynestad") is not a common name, there are some Norwegian and United States residents with this name. Most notably Brooklyn, New York has a relatively high concentration of Roinestads who migrated from Kvinesdal at various times.[citation needed]
