Derby North (/ˈdɑːrbi/) is a constituency formed of part of the city of Derby, represented in the House of Commons of the UK Parliament since 2019 by Amanda Solloway, a Conservative. Between 1983 and 2005, the seat was a bellwether; in 2010 and 2017 the seat leaned more to the left than the overall result. The seat has been relative to others a marginal seat since 2001, as well as a swing seat, as its winner's majority has not exceeded 8.6% of the vote since the 15.9% majority won at that year's general election. The seat has changed hands twice since then.
