Ignatz Anton Pilát (June 27, 1820 – September 17, 1870) was an Austrian-born gardener who migrated to the United States to work on the design and planting of New York City's Central Park.

In 1863, this industrious and modest man rose to be Chief Gardener and Superintendent of the park, a position he retained for the rest of his life.

About 1870 Pilát, redesigned Washington Square Park in New York, which at that time was laid out as a military parade ground.

Influenced by Frederick Law Olmsted, Pilát introduced more curvilinear paths to soften the military-straight lines of the old parade ground.

Pilát died of consumption at his home in New York on September 17, 1870, leaving "a wife and several children very poorly provided for".
