Coverage begins this weekend.
ITV will show one La Liga game per week for the rest of the season, it has been confirmed.
Starting with this Sunday's game between Levante and Real Madrid - the first ever La Liga match to be screened on free-to-air television in the UK and Ireland - several high profile matches will be shown on ITV4 from now until the end of the 2018/19 season.
They will also show weekly highlights as part of their deal.
Despite this new agreement, Eleven Sports remains the only place to watch all available LaLiga matches live in the UK and Ireland.
ITV will also not have first choice on games, and so will not be screening next month's El Clasico, as some reports originally claimed.
As well as the deal with ITV, La Liga's new broadcast partner Premier Sports is to offer four matches per round via its linear pay-TV channel.
This is available on Sky and Virgin TV platforms.
“This is a fantastic moment for La Liga in the UK and Ireland," said Javier Tebas, La Liga President.
"The best league in the world will be available to more fans than ever before.
"We are delighted to welcome Premier Sports and ITV Sport to our broadcaster stable in the UK and Ireland which already includes Eleven Sports.
"We are reaching the exciting conclusion to the season and millions of viewers will be able to enjoy the best teams and players in the world, as well as the passion and drama of La Liga.
