Julia Anne Goldsworthy (born 10 September 1978) is a British politician who served as the Member of Parliament (MP) for Falmouth and Camborne from 2005 until 2010. A member of the Liberal Democrats, she was narrowly defeated by 66 votes by the Conservatives in the new Camborne and Redruth constituency following boundary changes. In the House of Commons, she served as the Liberal Democrat spokesperson for Communities and Local Government. Afterwards, she worked as a special adviser.

Goldsworthy was born in Camborne, Cornwall, where her mother was a local teacher. She was educated locally at the St Meriadoc Primary School in Camborne before winning a scholarship to the independent Truro School. She took a gap year between school and beginning university in 1997, and in 2000 she graduated from Cambridge, with a BA (Hons) degree in History, having read for her degree at Fitzwilliam College. She then spent a year at Daiichi University of Economics in the Fukuoka Prefecture, Japan, and the following year completed a Postgraduate Certificate in Economics at Birkbeck College, London, in 2002.

Between 2002 and 2004, Goldsworthy worked in Westminster as an economics researcher for Matthew Taylor, the Liberal Democrat MP for Truro and St Austell, the seat adjacent to the one she would later represent. In 2004, she was appointed as a regeneration officer with the Carrick District Council where she worked until her election to Westminster less than a year later.

At the 2002 Lambeth Council Elections, Julia contested the Herne Hill ward. She polled 486 votes, finishing behind the Labour Party and Green Party.

Goldsworthy was elected to the House of Commons at the 2005 General Election for Falmouth and Camborne when she defeated the sitting Labour MP Candy Atherton. She gained the seat with a majority of 1,886 and made her maiden speech on 19 May 2005. She names former Cornish Liberal MP David Penhaligon (1944–1986) as her greatest hero. Her election in 2005 meant that the Liberal Democrats held all the Westminster Parliament seats in Cornwall, for the first time since 1923.

In 2005, she was appointed as a spokesperson on health by Charles Kennedy, and promoted in 2006 by new leader Sir Menzies Campbell as Vince Cable's deputy in the Treasury team. She was also member of the Public Administration Select Committee from 2005 until mid-2006. Julia Goldsworthy was promoted again in December 2007 to become the Liberal Democrat shadow secretary on Communities and Local Government. As an MP, she worked on issues such as the 'Axe the Tax' campaign against council tax, pensions, student tuition fees, health funding formulas and the abolition of central housing targets on local communities.

During her parliamentary career, Goldsworthy also used the social networking website Facebook as a way of gauging the opinions and views of her constituents, and this has led her to campaign for various issues. On 14 May 2008 in the House of Commons debates, she presented a petition on behalf of many thousands of people living in Cornwall who would like to see Cornwall be recognised as a network region on the website. Goldsworthy is a supporter of the Facebook Cornish Tickbox for the 2011 Census campaign.

Goldsworthy co-sponsored the Sustainable Communities Act 2007 (Amendment) Act 2010.
