Castle is coming to TNT.

The cable network has acquired the rights to the ABC series and will begin airing on TNT in the summer of 2012.

“With the addition of Castle, TNT continues to build a collection of hit shows that will perfectly complement our high-profile original series,” said Michael Wright, executive vice president, head of programming for TNT, TBS and Turner Classic Movies (TCM).

TNT also secured the right to Hawaii Five-0 earlier this year and will add it to its lineup in 2014.

Both shows join The Mentalist, which recently enjoyed a strong opening in its Wednesday 7-9 p.m. timeslot on TNT.
