The Mongolian gerbil or Mongolian jird is a rodent belonging to the subfamily Gerbillinae. Their body size is typically 110–135 mm, with a 95–120 mm tail, and body weight 60–130 g, with adult males larger than females. The animal is used in science and research or kept as a small house pet. Their use in science dates back to the latter half of the 19th century, but they only started to be kept as pets in the English-speaking world after 1954, when they were brought to the United States. However, their use in scientific research has fallen out of favor.
Gerbillinae is one of the subfamilies of the rodent family Muridae and includes the gerbils, jirds, and sand rats.

Most are primarily active during the day, making them diurnal, and almost all are omnivorous.
