Romsey Extra was a civil parish in the Borough of Test Valley and the English county of Hampshire. At the 2011 census, it had a population of 3,276, although due to the ongoing 800 home Abbotswood development that begun after the census was taken, it was likely to have risen significantly by the next Census and by 50% between 2012 and 2018. In 2014 there was a proposal for a new 1300 home development at Whitenap.
