Brookenby is a village and civil parish in the West Lindsey district of Lincolnshire, England. The village is situated 7 miles (11 km) north-east from Market Rasen. According to the 2001 census, it had a population of 742, falling to 665 at the 2011 census.
The village developed around the former RAF station, RAF Binbrook, with most of the population living in the former RAF housing. Since the name of the station came from an existing nearby village, the name 'Brookenby' was chosen in the 1980s when the new village was constituted. The name is believed to be derived from a nearby abandoned or plague village.
