The 2007 Grand Prix of Houston was the third round of the 2007 Champ Car World Series Season, held on April 22 at JAGFlo Speedway at Reliant Park.

Pole sitter Will Power was passed by Sébastien Bourdais and Justin Wilson at the drop of the green flag.

Oriol Servia, substituting again for the injured Paul Tracy, left the pits in 2nd, while Bourdais' teammate Graham Rahal got out in 3rd.

The top three remained static until lap 66 when Oriol Servia's green flag pit stop was balked by his teammate Mario Dominguez, dropping him all the way to 7th.

When Bourdais pitted on lap 68, Tristan Gommendy took the lead by staying out, gambling on a long-shot fuel strategy win.
