In-N-Out Burger is a regional American fast-food restaurant chain known for its burgers and fries. It was founded in 1948 by Harry and Esther Snyder in Baldwin Park, California, and is currently headquartered in Irvine, California. The company remains privately owned and operated by members of the Snyder family.

The first In-N-Out drive-thru opened in 1948, pioneering the modern fast-food drive-thru. The chain expanded gradually along the West Coast, prioritizing consistency, quality, and a limited menu. After Harry Snyder's death in 1976, control passed to family members, and growth continued under private ownership.

The core menu includes hamburgers, cheeseburgers, french fries, and beverages. The chain is known for unofficial additions such as Animal Style toppings and other items described as part of a secret menu. The company emphasizes freshness, says it uses fresh ingredients, and does not use freezers in its restaurants. Production and supply are vertically integrated to maintain quality across stores.

In-N-Out operates primarily in California and neighboring states with locations in Nevada, Arizona, Utah, Oregon, Colorado, and Texas. It has limited international exposure, with no current outlets outside North America.

The chain is notable for its simple, consistent menu, fast service, and strong customer loyalty, contributing to its iconic status in the American regional fast-food landscape.
