List of the Largest Ranches in the USA

How do you differentiate between a farm and a ranch? 

By definition, a farm is a piece of property that is used for growing crops and a ranch is a large piece of property that is used to raise livestock such as sheep and cattle.

On average, a farm is considered a ranch at about 450 acres although this varies significantly by state and cattle headcount. In the USA you will find small ranches with about 200 acres of land and 2,000+ acre properties which are considered large ranches.  The below list features the largest and most recognized ranches in the nation with over 500,000 acres of land.
