The Grand Prix of Baltimore presented by SRT was an IndyCar Series and American Le Mans Series race held on a street circuit in Baltimore, Maryland. The inaugural race was held September 4, 2011.[1] ESPN said it was the best inaugural street race in America in the last 30 years. The races are contested on a temporary street circuit around the Inner Harbor area of downtown Baltimore.[2]

Baltimore Racing Development signed a multi-year contract with IndyCar and the City of Baltimore to organize the race, but the city terminated their contract with BRD at the end of 2011 due to unpaid debts.[3] On February 15, 2012 it was announced that the city of Baltimore had entered into a five-year agreement with Downforce Racing to manage the race.[4] However, Downforce failed to fulfill their obligations to the city. On May 10, 2012 it was announced that Race On LLC. and Andretti Sports Marketing, led by racing legend Michael Andretti would take over the organization and promotion of the event.[5] Race On LLC is owned by Gregory O'Neill and J.P. Grant III. On september 13, 2013 it was announced that the grand prix would not be held in 2014 or 2015 due to scheduling conflicts.
