Uefa says it plans to double the number of women and girls in football across Europe over the next five years.
The 'We Play Strong' campaign will invest in initiatives with Uefa members from grassroots to elite levels.
Announcing the first dedicated strategy for women's football, Uefa president Aleksander Ceferin said: "Women's football is the football of today."

In case you missed it, on Friday, Arsenal signed Austria goalkeeper Manuela Zinsberger from Bayern Munich.
The 23-year-old helped the German giants lift back-to-back Bundesliga titles in 2015 and 2016.
The Gunners will be back in Women's Champions League action next season, having qualified as this season's winners of the Women's Super League. The other English qualifiers for 2019-20 are Manchester City.

Lyon have simply blown Barcelona away in the first half and Ada Hegerberg's 16-minute hat-trick has made Women's Champions League history.
Lyon 4-0 Barcelona
Barca should have a goal back, but Alexia heads just over the bar when unmarked at the far post at a corner.
Lyon 4-0 Barcelona
This is a huge challenge for Barcelona, from a psychological point of view now, just to keep this scoreline respectable. All their pre-match plans have gone out of the window.
They're still going about their passing stuff, giving it a go. You just never know, in football, but it's a long, long way back from here.
Lyon 4-0 Barcelona
Ada Hegerberg becomes the first player to score a hat-trick in a Women's Champions League final, with the competition having been rebranded from 2010.
The last player to net three times in a European women's final was Inka Grings for Duisburg of Germany in 2009, when the previously-named Uefa Women's Cup final was played over two legs.
Ada Hegerberg, hat-trick
It's four for Lyon and already we can say it's surely going to be their fourth consecutive European title.
Ada Hegerberg has a hat-trick, with her third goal in the space of 17 minutes.
It's an assist for England right-back Lucy Bronze, whose bent cross from the right is met by Hegerberg's brilliantly-timed run and tucked in first time. Ruthless.
Lyon 3-0 Barcelona
Barcelona's Lieke Martens - voted the player of Women's Euro 2017 - hasn't really had a chance to get in the game yet.
Lyon 3-0 Barcelona
France's Wendie Renard brings down England's Toni Duggan on the edge of the area and the defender is booked.
Lyon 3-0 Barcelona
In case you're not familiar with Lyon, they're yet to lose a single competitive game this season.
They recently sealed their 13th consecutive French title.
It's fair to say, they're pretty good.
Ada Hegerberg
Wow, this is astonishing, is the game over already? Lyon have a third!
Amel Majri squares the ball to Ada Hegerberg in the area and, as one of the world's best strikers, she doesn't miss those, 10 yards out.
Lyon 2-0 Barcelona
Ada Hegerberg gets a yellow card for a late one on Barcelona's María Leon. There was no malice in the challenge.
Ada Hegerberg
So simple. So clinical. So ruthless.
Lyon double their lead through Ada Hegerberg.
It's another ball down the right, again using the pace of Shanice Van de Sanden, who once more sends over a perfect, low cross and Ballon d'Or winner Hegerberg applies the tidy finish.
Lyon 1-0 Barcelona
Barca are looking vulnerable every time this formidable Lyon forward line get the ball.
Lyon 1-0 Barcelona
Lyon nearly add to their lead but Shanice Van de Sanden's header - which looks to be going just wide anyway - is blocked and cleared.
Dzsenifer Marozsan
But it hasn't taken long for the holders to go in front!
Seconds after Toni Duggan went close at the other end, Lyon break and use the pace of The Netherlands' Shanice Van de Sanden down the right.
Her cross is turned home first time by Germany's Dzsenifer Marozsan. A very well-worked goal but it was all too easy.
Lyon 0-0 Barcelona
England's Toni Duggan gets on the ball for the first time, down on the left, but her through-ball is intercepted by the towering French centre-half Wendie Renard.
Moments later, Duggan has the game's first chance, but she fires wide from just inside the area.
It's a bright start for Barcelona. We're used to seeing Duggan bury those kinds of chances.
