The Samsung Galaxy Note series is a series of high-end Android-based smartphones and tablets developed and marketed by Samsung Electronics. The line is primarily oriented towards pen computing; all Galaxy Note models ship with a stylus pen and incorporate a pressure-sensitive Wacom digitizer. All Galaxy Note models also include software features that are oriented towards the stylus and the devices' large screens, such as note-taking and digital scrapbooking apps, and split-screen multitasking.

The Galaxy Note smartphones have been considered the first commercially successful examples of "phablets"—a class of smartphone with large screens that are intended to straddle the functionality of a traditional tablet with that of a phone.
