Gilroy Gardens, Horticulture-themed amusement park in Gilroy, California, US

Gilroy Gardens is a horticulture-themed amusement park on 536 acres (217 ha) in Gilroy, California, designed and built by Michael Bonfante. It holds 19 rides, 27 attractions and six gardens, among them a garden of 24 Circus Trees shaped by Axel Erlandson into basket-weave patterns and hearts. The city of Gilroy owns the park, and the nonprofit Gilroy Gardens, Inc. operates it.

Michael and Claudia Bonfante sold their Nob Hill Foods supermarket chain to Raley's to fund the park, which they built gradually over 25 years on land first used as Tree Haven, a commercial nursery and staff recreation site. It opened to the public in June 2001 as Bonfante Gardens and was renamed Gilroy Gardens in February 2007. The city of Gilroy bought the park on March 5, 2008.

Gilroy Gardens takes its identity from the agricultural town around it: garlic, artichokes and strawberries shape ride names such as Garlic Twirl and Artichoke Dip. The park's mascots, Gil and Roy, appeared in 2007 and 2013, and seasonal characters join events like Great Big Boo and North Pole Nights.

The park sits at 3050 Hecker Pass Highway in Gilroy, Santa Clara County, with entrances and paths laid out around six gardens and the ride areas. Admission is by paid ticket, and the grounds cover 536 acres, so allow time to walk between the gardens and attractions. The Sky Trail Monorail crosses the Monarch Butterfly Greenhouse.

The Circus Trees were shaped by Axel Erlandson, a Swedish immigrant and self-taught grafter who bent and joined trunks into basket-weave patterns and hearts. Michael Bonfante bought the collection in 1985 and moved 24 of the trees to the park, where they remain the most photographed feature.
