Rentschler Field (IATA: EHT, FAA LID: CT88) was an airport in East Hartford, Connecticut in use from 1933 to 1999.

Originally a military facility, later a private corporate airport, it was decommissioned in 1999, after which the football stadium of the same name was built on the site.

In the mid-1990s, the Six Flags corporation considered using the vacated acreage as the site for a new amusement park property, following community pushback in the southeastern Connecticut tourist area surrounding their plan to use property in Stonington, Connecticut under an agreement with the Mashantucket Pequot Tribal Nation.

City of East Hartford leadership supported the introduction of a Six Flags park to Rentschler Field, with key points including the site's large size, proximity to Hartford and central location near major thoroughfares Interstate 91 and Interstate 84, with the possibility to attract people from New York City and Boston, Massachusetts in addition to Southern New England.

Students and fans of the UConn team commonly refer to the new stadium as "The Rent", an homage to the original name.
