The Zune HD is a portable media player in the Zune product family released on September 15, 2009 by Microsoft. It is a direct competitor with the Apple iPod and iPhone series of mobile devices. It was initially released in 16 and 32 GB capacities. A 64 GB version was released on April 9, 2010. It utilizes a touchscreen interface for navigation and includes Wi-Fi for synchronization, access to the Zune Marketplace and Web browsing.

The Zune HD utilizes the Nvidia Tegra APX 2600 chip, allowing it to play 720p video through the optional HDMI Zune dock on a high-definition television. Otherwise, content will be scaled down to 480x272 pixels on the player's OLED touchscreen.

Soon after Apple released the iPod Touch^{[citation needed]}, Microsoft R&D department head, Robbie Bach began work on a touch-screen Zune player to combat it. The department started immediately on reworking the Windows CE-based OS of the older Zune to suit the new multitouch PMP. Astro Studios was contracted to design the Zune HD's aluminum casing. On June 19, 2009, Zune Insider host Matt Akers confirmed that the Zune HD would have an nVidia Tegra APX 2600 chip and OLED touchscreen.^{[citation needed]}
