The 20 clubs in England's top flight have unanimously agreed the price cap which will come into force at the start of next season.
There have been a series of protests about ticket prices at Premier League grounds around the country this season and the Premier League has underlined the importance of supporters to the game.
"Clubs know that away fans have a unique status. They are essential for match atmosphere and stimulate the response from home fans that distinguishes Barclays Premier League matches from those of other leagues," read an official statement.
"Away fans have additional travel costs and pay individual match prices, as season ticket and other discounts are not available to them and the responsibility for them is shared between Clubs and therefore it is right that there is a collective initiative to help them.
"At their last meeting on 4 February, 2016, the Clubs unanimously agreed that more should be done to help away fans and, after consideration of a range of options, have now decided to introduce the new £30 maximum price for away tickets."
