'''''Citrus''''' is a [[genus]] of [[flowering plant|flowering]] trees and [[shrub]]s in the family [[Rutaceae]]. Plants in the genus produce '''citrus fruits''', including important [[crops]] such as [[Orange (fruit)|oranges]], [[Mandarin orange|mandarins]], [[lemon]]s, [[grapefruit]]s, [[pomelo]]s, and [[lime (fruit)|limes]].

''Citrus'' is native to South Asia, East Asia, Southeast Asia, [[Melanesia]], and Australia. [[Indigenous peoples|Indigenous people]] in these areas have used and domesticated various species since ancient times. Its cultivation first spread into [[Micronesia]] and [[Polynesia]] through the [[Austronesian expansion]] ({{circa|3000}}–1500 BCE). Later, it was spread to the Middle East and the [[Mediterranean]] ({{circa|1200 BCE}}) via the [[incense trade route]], and from Europe to the Americas.

Renowned for their highly fragrant aromas and complex flavor, citrus are among the most popular fruits in cultivation. With a propensity to hybridize between species, making their taxonomy complicated, there are numerous varieties encompassing a wide range of appearance and fruit flavors.
