The charity wants to persuade young women that voting can have an impact on issues they care about.
It has identified issues such as sex and relationship education, safety on the streets and bullying, as areas of concern for young women.
The campaign will take the form of cartoons sent to youth centres and cinemas.
MPs in England and Wales are also being targeted with the cartoons to ensure they are aware of the areas of policy that young women prioritise.
'We are saying to parliamentary candidates: These are the issues young women care about - what are you going to do about them?' said YWCA campaigns officer Antonia Bance.
Parliamentary candidates are being asked to pledge their support to finding solutions to the problems. The charity will emphasise research that shows that only 18 per cent of young women aged 18 to 24 intend to vote in the election.
Youth-work trade press are being targeted, along with local radio stations, regional newspapers and women's and social affairs editors on nationals.
Local YWCA groups will also invite candidates from each of the main parties to their centres, giving young women the chance to question MPs about the issues.
