Chiraprapha

Chiraprapha Thewi (, Chiraprabhādevi; ), also spelt Chirapraphathevi, known in the Chiang Mai Chronicle as Phra Pen Chao Maha Chirapabha Devi (; ) was the Queen consort of Ket, the 12th monarch of the Kingdom of Lan Na, and the mother of Thao Chai, the 13th monarch.

She later ascended the throne as the 14th monarch of Lan Na, becoming the first Queen regnant of the kingdom following her husband's assassination, and reigned from 1545 to 1546. During her reign, the northern principalities fell into turmoil due to power struggles between nobles and members of the royal family. The kingdom became weakened, facing military threats from both the north and south, namely from the Burmese and Ayutthayan armies. This coincided with the reign of Chairachathirat of Ayutthaya, who led a military campaign that reached Chiang Mai.
