The Royal Holyn Defence Forces is the military force of Holynia comprising the Holyn Ground Force, Royal Holyn Air Force, Royal Holyn Navy, Royal Holyn Strategic Forces, along with two independent arms of service; the Royal Holyn Marines and the Holyn Airborne Assault Forces.

Holynia has maintained a standing military since 1743, however the current interation traces its roots to the Holyn People's Army founded in 1925. This force was reformed in 1950 into the Holyn Armed Forces. The collapse of communist Holynia and separatist rebellion in Bogoria saw the Holyn Armed Forces begin to splinter and disintegrate. Elements of the military were accussed of war crimes, including ethnic cleansing. The military was reorganized in 2001 as the Holyn Defence Forces, adding the Royal prefix in 2002. The military underwent rebuilding and modernization in the 2000s and 2010s.

The head of the military is the Holyn monarch, currently King Mikulas I, the figure that service members swear allegiance to. The constitution, however, vests de facto executive control of the military in the Prime Minister and Minister of Defence. The Chief of the General Staff leads the day to day operations of the military.

The Royal Holyn Defence Forces is authorized for 493,700 personnel under the FY2021 budget. The military is entirely volunteer based, with conscription ending in 2005. Civilians must still register for conscription once they reach 18 years of age, however, are not called for service. The military budget of Holynia is around $101.3 billion. Three branches of the military operate nuclear weapons, the Royal Holyn Air Force, Royal Holyn Navy and the Holyn Strategic Forces. Two independent uniformed security forces are seperate of the Royal Holyn Defence Forces and fall under the two Principalities of Holynia, Hornatyia and Masovia. These are the Hornatyian National Guard and Masovian National Guard.
