Hildon是为了行动设备（PDA，手机等）而开发的应用框架，运行在 Linux 操作系统上。

它是由诺基亚公司在 Maemo 操作系统开发，现在已经成为 GNOME 的一部份。它主要是为了提供一个可以触摸的界面而开发的。

Hildon is an application framework originally developed for mobile devices (PDAs, mobile phones, etc.) running the Linux operating system as well as the Symbian operating system. The Symbian variant of Hildon was discontinued with the cancellation of Series 90. It was developed by Nokia for the Maemo operating system and is now a part of GNOME. It focuses on providing a finger-friendly interface. It is primarily a set of GTK+ extensions that provide mobile-device–oriented functionality, but also provides a desktop environment that includes a task navigator for opening and switching between programs, a control panel for user settings, and status bar, task bar and home applets. It is standard on the Maemo platform used by the Nokia Internet Tablets and the Nokia N900 smartphone.
