Bandon (/ˈbændən/) is a city in Coos County, Oregon, United States, on the south side of the mouth of the Coquille River. It was named by George Bennet, an Irish peer, who settled nearby in 1873 and named the town after Bandon in Ireland, his hometown. The population was 3,066 at the 2010 census.

Before 1850, the Coquille Indians lived in the area. Then in 1851, gold was discovered at nearby Whiskey Run Beach by French Canadian trappers, though the gold rush did not have much of an impact on the area. In 1852, Henry Baldwin, from County Cork, Ireland, was shipwrecked on the Coos Bay bar and walked into this area. The first permanent European settlers came in 1853 and established the present town site. In 1856, the first conflicts with Indigenous Americans in the United States arose and those were sent to the Siletz Reservation. In 1859, the boat Twin Sisters sailed into the Coquille River and opened the outlet for all inland produce and resources.
