Jane Maria Collins (born 17 February 1962) is a British politician and horse show-jumper who served as a Member of the European Parliament (MEP) for Yorkshire and the Humber from 2014 to 2019. She was elected in May 2014 as a member of the UK Independence Party (UKIP), but defected to the Brexit Party in 2019 in the last months of her membership of the European Parliament.

Collins served as UKIP's spokesperson on Employment law, Home Affairs and most recently on Animal Welfare. On 15 April 2019 she announced that she was leaving the party to join the Brexit Party.

Collins was born in Pontefract, West Riding of Yorkshire and attended East Hardwick Junior School and Pontefract and District Girls High School, leaving at 18 with four GCE O-levels and a GCE A-level in Art.

On leaving school, Collins opted against going to college, preferring to develop an equestrian career. She began her equestrian career with a racehorse training establishment in Moss, South Yorkshire. An equine physiotherapist, she met Katie Bloom with whom she formed a partnership in 1995. Katie Bloom was (and remains) married to Godfrey Bloom, who later became a UK Independence Party (UKIP) MEP. Collins became interested in the party, which she joined in 2003.

Interviewed by the Observer ahead of the September 2014 UKIP conference and therefore unable to discuss their new policies, Collins described herself as a "progressive libertarian". Referring to comments made by Godfrey Bloom on international aid (in a speech in which he referred to "Bongo-Bongo land"), she said that they were valid but badly expressed. She was concerned about "a developing health problem" in Sheffield in relation to the Roma community of Slovak origin. She claimed they had a higher incidence of hepatitis B, the subject of a planned vaccination program, which would put a greater strain on the health service. She also called for those indigenous children who are in close contact with the Roma to be vaccinated as well. In conclusion, journalist Daniel Boffey said Collins would continue Bloom's tradition of stirring controversy.

Collins stood for UKIP in the March 2011 Barnsley Central by-election triggered by the resignation of Labour MP Eric Illsley over the UK parliamentary expenses scandal. She came second to Labour's Dan Jarvis, winning 12% of the vote. This was the first time a UKIP candidate had come second in any election.

She again stood for UKIP in the November 2012 Rotherham by-election triggered by the resignation of Labour MP Denis MacShane, also over the expenses scandal. She came second to Labour's Sarah Champion, winning almost 22% of the vote. It was at the time the highest share of the vote achieved by UKIP in a by-election. The by-election took place almost parallel with the inaugural police and crime commissioner elections. The timing combined with press reports concerning child sexual exploitation in Rotherham led to questions about the selection of the Labour candidate for police and crime commissioner, Shaun Wright who had been the cabinet member of the council responsible for children's services. During the by-election campaign a row also emerged after Rotherham's Labour council removed three foster children from the care of their foster parents, which the Daily Telegraph wrongly attributed to their membership of UKIP. However, in May 2013, Rotherham council apologised, saying that communication about the decision gave the impression that it related to the couple's UKIP membership. This impression was incorrect; the children were removed because it was in their "best interests", though full details couldn't be given "for legal reasons". The council said it had "taken action to strengthen the way it made decisions and how it communicated information."

She was selected to top the party's regional list for Yorkshire and the Humber in the 2014 European Parliament elections. Former UKIP MEP Godfrey Bloom stated that he gave her his "wholehearted support" and that she "is almost certainly going to be the next UKIP MEP".
