In oral traditions associated with the early history of the Tagalog people, Empress Sasaban or Dayang Sasaban (Baybayin: ᜐᜐᜊᜈ᜔ , Javanese: ꦱꦼꦒꦮꦺꦴꦤ꧀) is said to have been a 14th Century noblewoman (Dayang) of the Tagalog polity of Namayan, on the shores of the Pasig River in Luzon.^[1]: 47,51

In the legends, she leaves Namayan to marry to an "Emperor Soledan" (also identified as "Anka Widyaya") of the Majapahit. At the Majapahit court, she gives birth to a son named Balagtas,^[1]: 51 who eventually returns to Luzon to rule over Balayan and Taal, and marry Princess Panginoan of Pasig.^{[1]: 51 [2]}

However, there is no mention of her in the Negarakertagama, thus her existence is unsure.^{[citation needed]}
