The Town of Estella is located in Chippewa County in the U.S. state of Wisconsin. The population was 433 at the 2010 census.

The shape of Estella is irregular. The east end is a rectangle 6 miles (10 km) north to south and 3 miles (5 km) wide. The west end follows the Chippewa River, except for a section which is part of the city of Cornell.

According to the United States Census Bureau, the town has a total area of 32.0 square miles (82.9 km), of which 31.4 square miles (81.4 km) is land and 0.62 square miles (1.6 km), or 1.89%, is water.

The general area that would become Estella was first surveyed in 1847 by a crew working for the U.S. government. In 1852 a different crew marked all the section corners of the township, walking through the woods and wading the rivers, measuring with chain and compass. When done, the deputy surveyor filed this general description of the six by six mile square which overlays most of the modern township:

This Township contains a number of Cedar & Tamarac swamp, all unfit for cultivation. The Surface generally level(?) and heavily(?) timbered with Pine, Hemlock, Tamarac Sugar Maple & Birch. Soil second to third rate and a part fit for cultivation. Chippewa and Fisher Rivers runs through the NorthWest corner of this Township. The banks of this River are high and generally covered with pine and Hemlock timber.

The town was named for Laura Estella Flint, the wife of Warren S. Flint, a local business owner who became the first postmaster in 1886.
