Ansnorveldt is a hamlet located at the northeastern extent of King Township, in Ontario, Canada.

Whereas most of King township is in the Oak Ridges—Markham electoral district, Ansnorveldt and all other portions of King north of Highway 9 are part of the York—Simcoe electoral district, represented federally by Scot Davidson of the Conservative Party of Canada and provincially by Caroline Mulroney of the Progressive Conservative Party of Ontario.

Located in the fertile Holland Marsh, the area is considered to be the Breadbasket of Ontario.

The Ansnorveldt Wetland Complex, which is a provincially significant wetland area, is located on the edge of the Holland Marsh; its southern extent reaches the northern slopes of the geologically important Oak Ridges Moraine.

The wetlands in the complex are hydrologically connected along a discharge zone at the base of the Oak Ridges Moraine.
