Dayang Kalangitan (r. 1450–ca. 1515) is the only recorded queen regnant of the pre-Hispanic Philippine Kingdom of Tondo. The eldest daughter of Rajah Gambang and co-regent with her husband, Rajah Lontok, she is considered one of the most powerful rulers in the kingdom's history. She is also notably the last animist ruler of the kingdom, which encompassed land along the banks of the Pasig River in Metro Manila.
