An orange grove is an orchard of cultivated orange trees. The term "grove" refers to a group of trees planted and cultivated for fruit or nut production. Orange groves can be found in various places around the world, including the United States, Australia, and South Africa.

In California, the California Citrus State Historic Park is an example of an orange grove preserved from a bygone era. This park preserves some of the rapidly vanishing cultural landscape of the citrus industry and tells the story of this industrys role in the history and development of California. Furthermore, it recaptures the time when "Citrus was King" in California, recognizing the importance of the citrus industry in southern California.

The difference between an orchard and a grove is that an orchard is an area of land devoted to the cultivation of fruit or nut trees, while a grove is a small wood or stand of trees lacking dense undergrowth.
