Corby is a town and borough located in the county of Northamptonshire, England.

It is located 23 miles (37 km) north-east of the county town, Northampton. The borough had a population of 61,300 at the 2011 Census. Figures released in March 2010 revealed that Corby has the fastest growing population in both Northamptonshire and the whole of England. The Borough of Corby borders onto the Borough of Kettering, the District of East Northamptonshire, the District of Harborough and the unitary authority county of Rutland. The town was at one time known locally as "Little Scotland" due to the large number of Scottish migrant workers who came to Corby for its steelworks. Recently, Corby has undergone a large regeneration process with the opening of Corby railway station and Corby International Pool in 2009 and the Corby Cube Building opening in 2010. This is home to Corby Borough Council and is a large 450 seat theatre.
