The Compaq Contura was a line of notebook computers produced by Compaq Computer Corporation.
The main Contura series included models 3/20, 3/25, 3/25c, 4/25, 4/25c, 4/25cx, 400, 400C, 400CX, 410, 410C, 410CX, 420C, 420CX, 430C, and 430CX. These were mid-size notebooks, not ultra-portable subnotebook computers. The "X" designation denoted an active matrix screen.

They were released in 1994 and originally ran MS-DOS and Windows 3.1. They were also able to run Windows 95 after its release in 1995. They were similar to the Contura line of laptop computers but smaller. It is interesting to note that while the GPU can produce color, the datasheet for the device states it is incapable of producing color graphics.

The line of handheld devices starting from the Aero 1550 Pocket PC were finally moulded into the iPAQ line of handheld devices, which is currently handled by Hewlett-Packard, after their acquisition of Compaq.
