The HTC HD2 (also known as the HTC T8585, HTC T9193 and HTC Leo), is a smartphone in the HTC Touch family designed and manufactured by HTC. The HD2 natively runs the Windows Mobile 6.5 operating system, and was released in Europe in November 2009, in Hong Kong in December 2009, and in other regions including North America in March 2010. The phone is the successor to the HTC Touch HD, and is succeeded by the HTC HD7.

Rumors of the HTC HD2 began appearing in September 2009. It was codenamed Leo, although a decal on the back cover conflictingly identified it as the Pro.Three (which indicates it may have been intended as a bridge between the HTC Touch Pro and HTC Touch), and the "About" info in Bluetooth as the HD2. The specifications sheet released turned out to be true when the HD2 was launched, with the exception of the listed 320MB of RAM, compared to the final 576MB (448MB available to user) of RAM.

It is the first smartphone with a 4.3-inch touchscreen, the first Windows Mobile 6.5 phone with a multitouch capacitive screen and HTC Sense, and the second smartphone with a Qualcomm Snapdragon CPU (the first being the Toshiba TG01). The Snapdragon CPU is clocked at 1 GHz, but automatically underclocks itself to 553 MHz if extra processing power is not needed. Tweaks have been made however, to clock the processor dynamically from 96 MHz to 1.61 GHz.

The HD2 is fitted with an Asahi Kasei AK8976A magnetometer. The magnetometer is used for applications such as the pre-loaded digital compass.

HTC officially sells an optional capacitive stylus pen for the HD2 to aid navigation through the interface. Some Windows Mobile applications were designed to be used with a stylus, rather than finger-touch, and still need a stylus pen to be used effectively.
