Van Vleck House and Gardens is a former private estate run as a non-profit community resource in Montclair in Essex County, New Jersey, United States. It features a public botanical garden of mostly ericaceous plants that has been developed over several generations. The display of rhododendrons and azaleas shows numerous hybrids, several named after members of the Van Vleck family.
The property had been in the hands of the Van Vleck family until 1993 when it was turned over to The Montclair Foundation. The main house, built in 1916 by Joseph Van Vleck Jr. as a Mediterranean villa, is available for events by non-profit organizations. A Chinese wisteria that was planted in 1939 climbs around the pillars of the back portico.
