King Borommarachathirat I or King Borom Rachathirat I (Thai: สมเด็จพระบรมราชาธิราชที่ ๑), also known as Khunluang Pha Ngua (Thai: ขุนหลวงพะงั่ว); 1370–1388), was the third king of Ayutthaya Kingdom. He was the older brother of King U-thong's consort, and was King Ramesuan's uncle.
As the lord of Suphanburi, a powerful rival of Ayutthaya, he forced King Ramesuan from power and took the throne of Ayutthaya. Known as a great warrior, his reign marked the expansion of Ayutthaya to the north. He suppressed a rebellion in Sukhothai Kingdom (1371–78) and subjugated major northern powers such as Phitsanulok. Invading Chiang Mai, his forces were defeated and repulsed at the Battle of Sen Sanuk, near Chiang Mai.
After his death in 1388, his son, Thong Lan reigned for only a week. Ramesuan, who had previously retreated to Lavo, returned and toppled him. Ramesuan eventually assumed the throne, as the king for the second time.
