O'Rourke's Diner is a diner located in the Main Street Historic District in Middletown, Connecticut.
On August 31, 2006, O'Rourke's Diner suffered tremendous damage from a fire that broke out after a hamburger steamer was left on overnight. Because the diner did not have fire insurance, fundraising efforts were launched to cover the estimated $350,000 cost of repairs. By June 2007, $180,000 had been raised and preparations for reconstruction were underway. On February 11, 2008, following successful renovations which included assistance from the local community and Wesleyan University, O'Rourke's was reopened at 5:00 am.
