The Kenworth W900 is a model line of conventional-cab trucks that are produced by the Kenworth division of PACCAR. The replacement of the 900-series conventional, the W900 is produced as a Class 8 conventional-cab truck primarily for highway use. The "W" in its model designation denotes Worthington, one of the two founders of Kenworth.^[1] 63 years after its introduction, the W900 is currently in its third distinct generation (introduced in 1982).

At its introduction, the W900 conventional was introduced alongside the K100 COE. As the Kenworth model line was expanded, the W900 became its flagship conventional, with its cab structure used across other model families. Through its production, the W900 has competed against a wide variety of model lines; among owner-operator drivers, the W900 created a rivalry with the Peterbilt 379 (from Paccar sister division Peterbilt) and its successor Peterbilt 389. The model line also remains a popular basis for truck customization, with owners adding additional chrome trim, wheels, lighting, and paint.

Currently, Kenworth produces the W900L at its Renton, Washington assembly facility.^[2] In 2018, the W990 was introduced as an all-new flagship conventional, phased in to replace shorter-hood models of the W900 line.
