This summer is bound to be incredible, especially with so many of our favorite pop acts hitting the road! One Direction, Austin Mahone, Little Mix and Fifth Harmony are all going on tour this summer, and we are super pumped to see them all in concert. But with so many incredible acts, there's bound to be one that just makes you a tiny bit more excited than the rest. It's a tough choice, but here ya go: Whose summer tour are you most psyched to see?

The guys of One Direction are embarking on their Where We Are World Tour this spring, and it's going to be unbelievable for so many reasons. As if the guys weren't swoon-worthy enough, they recently just released their 'You and I' music video, and you know they're looking good in that vid. Plus, we just saw the first pictures of their tour stage, and it is beyond enormous -- which leaves plenty of room for Harry, Niall, Liam, Louis and Zayn to perform and even kick up some awesome hijinks.

Austin Mahone recently announced his 2014 tour dates, and he will travel across the U.S. beginning this July in support of his much-anticipated full-length album, 'The Secret.'  Mahone's tour will not disappoint, as the Vamps, Fifth Harmony, Shawn Mendes and Alex Angelo will also open on select dates. Amazing!

We already know that Fifth Harmony will be touring with Austin Mahone starting in July, but they are also embarking on their own headlining tour this summer, starting this May and going straight through until the end of June -- though there are one-off dates in July and August as well. (In addition to Mahone's tour, of course!) Fresh off of the Neon Lights Tour with Demi Lovato, the ladies of 5H can't wait to hit the road again, and this time on their own '5th Time's a Charm Tour.' You know this one will be awesome!

The Salute Tour will be a huge one for Little Mix -- the girls will be embarking on their first-ever headlining North American tour! While the tour will kick off in Florida on Sept. 10, the date is technically still summer -- considering fall won't arrive until several weeks later. The ladies of Little Mix will have some friendly competition during their tour, considering Perrie Edwards' fiancé, Zayn Malik, will be on tour with 1D at the same time. But they will have just missed their Neon Lights tour mates Fifth Harmony, whose dates end right before Little Mix's begin.
