This is a list of orders of battle for the First Ava–Hanthawaddy War in which the Royal Ava Armed Forces and their allies Myaungmya armed forces fought the Royal Hanthawaddy Armed Forces between 1385 and 1391.

The orders of battles for Ava in this article are sourced from the main royal chronicles—the Maha Yazawin, the Yazawin Thit and the Hmannan Yazawin, which primarily narrate the war from the Ava side, and provide a specific order of battle for each of the Ava campaigns; the chronicles also typically (but not always) provide the opposing forces' strength as part of their narratives.^{[note 1]}

The extant information for the orders of battles for Hanthawaddy Pegu is not as detailed. The Razadarit Ayedawbon chronicle, which narrates the war from the Hanthawaddy perspective, provides only occasional facts and figures on the Hanthawaddy forces, and even less on the opposing forces. Therefore, this article uses the limited orders of battle information on the Hanthawaddy side reported in the main chronicles.^{[note 2]}

The military strength figures in this article have been reduced by an order of magnitude from those reported in the chronicles, following G.E. Harvey's and Victor Lieberman's analyses of Burmese chronicles' military strength figures in general.^{[note 3]} Specifically for this war, historians' estimates range from 12,000 to 30,000+ troops for Ava (as opposed to 130,000 to 290,000 infantry reported in the chronicles).^{[note 4]}

In all the three invasions, Ava raised the vast majority of its regiments from districts around the capital (Ava, Pinle, Pinya, Myinsaing, Sagaing); central and southern districts along the Irrawaddy river (Pagan, Sagu, Salin, Pakhan Gyi, Myede and Prome); and south and southeastern districts (Nyaungyan, Yamethin, Taungdwin, Toungoo).^[1][2] Of its northern districts only Kale contributed a regiment in the first and second invasions while Dabayin, Amyint and two Shan regiments participated in the second invasion.^[3][2] However, after its war with the northern Maw kingdom (1387–1389/90),^[4] Ava did not include any northern regiments in its third invasion of Hanthawaddy Pegu in 1390–1391.^[5][6][7]

The Hanthawaddy army that withstood Ava's first two invasions consisted of troops from the central Hanthawaddy province (Dala, Dagon, Hlaing, Hmawbi and Pegu), the only province King Razadarit controlled.^[8] It was only in 1390 after Razadarit had conquered Martaban and Myaungmya provinces that the Hanthawaddy army was able to field its largest force, drawn from all three provinces.^[5][9]
