ASUS ZenBook

Asus Zenbook is a line of consumer-oriented high-end notebook computers produced by Asus. The first Zenbooks were released in October 2011 as Ultrabooks, and the original range of products has since been expanded to models ranging from smaller and power efficient notebooks to high-end and larger laptops with additions like discrete graphics processing units. As of 2025, the Asus Zenbook A serves as the company's flagship notebook computer.

The series is positioned by Asus as part of the thin-and-light segment within the premium consumer market. Asus designed the Zenbooks with brushed aluminium chassis and high rigidity, rather than plastic, the usual laptop construction material. A pattern of concentric circles on the lids is said to represent ripples in water and reflect the "zen philosophy" that designers wanted to portray when creating the laptops. Asus has also described its design approach as influenced by reductionism, aiming to simplify form while retaining functionality. As of 2024 there are various series including the standard Zenbook, extra slim and light Zenbook S, performance-oriented Zenbook Pro with dedicated graphics cards, convertible Zenbook Flip, dual screen Zenbook Duo, foldable tablet Zenbook Fold and portable Zenbook A.
