Which episode features Leslie Knope and Ben Wyatt's wedding?

The episode featuring Leslie Knope and Ben Wyatt’s wedding is “Leslie and Ben.” It is the 14th episode of Parks and Recreation’s fifth season and originally aired on February 21, 2013.

The couple had planned to marry three months later, but their wedding plans are disrupted during a Pawnee Commons fundraising gala. After Councilman Jamm ruins the evening and Ron Swanson punches him, Leslie briefly believes the wedding must be postponed. Her friends then secretly reorganize the Parks Department office for an intimate ceremony.

The episode is notable because the wedding is assembled in roughly two hours, with Leslie’s coworkers contributing whatever they can. Ron walks Leslie down the aisle, and the ceremony emphasizes the close friendships at the center of the series.

A common mix-up is “Emergency Response,” the preceding episode, which sets up the gala but does not contain the wedding. The episode’s title is also sometimes written with an ampersand in informal listings, but “Leslie and Ben” is the canonical title.
