The 2010 Toyota Grand Prix of Long Beach was the fourth round of the 2010 IndyCar Series season, and took place on April 18, 2010.

The race was contested over 85 laps of the 1.968-mile (3.167 km) street course in Long Beach, California, and was telecast by Versus in the United States.

Justin Wilson attempted to go down the inside of Ryan Hunter-Reay, the man who started alongside Power on the front row, but he eventually settled into third spot.

This status quo was maintained till lap 17 when, coming off turn 11, race leader Power hit the pit lane speed limiter button by mistake.

Kanaan, in fourth, was now 15 seconds behind the leader, and fifth-placed Briscoe once again found himself harassed by Scott Dixon after the latter swapped places with Castroneves during the pit stops.

After his earlier incident with Lloyd, he was more cautious in dealing with the lapped cars, and by the time he had got around Matos, Hunter-Reay was over 5 seconds up the road.
