Greenfield is a city in Monterey County, California, United States.

In 1902, the California Home Extension Association, founded by John S. Clark, purchased 4,000 acres (1,600 ha) of land that had been part of Rancho Arroyo Seco, a Mexican land grant deeded to Joaquín de la Torre in 1840.

The organized water canal system and ideal growing conditions attracted people of Danish, Swiss and other nationalities from surrounding areas to settle in this new colony.

Instead, the community named the town after one of its early founders and president of the Association, Edward Greenfield.

[5] Due to its location near California's Central Coast, the area is filled with rich soil and desirable climate, ideal for many agricultural and wine companies.

As of the 2007 California Department of Finance estimate, there were 16,629 people in 2,643 households, including 2,360 families, in the city.

In recent years, the town has seen an influx of immigrants from the Mexican state of Oaxaca.

Probably the largest single bloc of such immigrants are speakers of the Copala Triqui language, who have fled from poverty and long-standing armed conflict in their native region.

Television service for the community comes from the Monterey-Salinas-Santa Cruz designated market area (DMA).

The city of Greenfield is centered in one of the most productive agricultural areas in the world.

More than $3 billion (US) worth of fruits, vegetables and nuts are produced and shipped annually across the U.S. and abroad.

[12] As a result, many major vegetable producers are headquartered in the nearby city of Salinas.

The area is also known as a premier wine grape growing region due to the rich soil and desirable climate.

Vineyards, wineries and wine tasting rooms continue to expand throughout the region.

On February 27, 2008, Greenfield Elementary was placed under no help due to the school's achievement in raising their Standardized Testing and Reporting (STAR) Results under the No Child Left Behind Act for the past five years by Governor Arnold Schwarzenegger and Superintendent of Public Instruction Jack O'Connell.

A northern campus for the Yanks Air Museum of Chino, California is under construction in Greenfield on a 440 acres (1.8 km2) plot known as the Hanson Ranch, which was purchased in 1994 by museum founders Charles and Judith Nichols.

The new airstrip will use the original location and will see World War II aircraft landing there some 75 years later.

Named after the first mayor of Greenfield, it will showcase the history of the city as far back as 1905.
