The Palm Pre (styled palm prē, pronounced as the English prefix pre, /ˈpriː/, known internally as the Castle) is a multimedia smartphone designed and marketed by Palm with a multi-touch screen and a sliding keyboard. The phone was launched on June 6, 2009, and is the first to use Palm's new Linux-based operating system, webOS. The Pre functions as a camera phone, a portable media player, a GPS navigator, and an Internet client (with text messaging, e-mail, web browsing, and local Wi-Fi connectivity).

The Pre has received positive reviews from technology critics, winning CNET's Best in Show, Best in Category: Cell Phones & Smartphones, and People's Voice for CES 2009.
