The YMS-15 Gyan is a mobile suit that appears in the TV anime Mobile Suit Gundam.

The YMS-15 Gyan was developed by Zimmad in the late stages of the One Year War for the Principality of Zeon's second phase mainstay mobile suit development project. It was designed with exceptional close combat ability in anticipation of melee combat against the Earth Federation Forces' mobile suits. However, its focus on close combat resulted in lower versatility. Ultimately, Zeonic's MS-14 Gelgoog was selected as the second phase mainstay mobile suit due to its superior general performance and versatility, though the Gyan's basic performance was said to be superior to the Gelgoog.

Though the Gyan's reactor output was not sufficient for a beam rifle, it was more than enough to power its primary weapon, a custom beam saber. Its only other weapon was the missile shield, an equipment that combined offensive and defensive capabilities. Thanks to its use of the fluid pulse accelerator, as well as its arms and hands being tuned specifically for close combat, the Gyan's responsiveness and range of motion were extremely high among One Year War-era mobile suits.
