Mazu or Matsu is a sea goddess in Chinese folk religion, Chinese Buddhism, Confucianism, and Taoism. She is also known by several other names and titles. Mazu is the deified form of Lin Moniang (Chinese: 林默娘; pinyin: Lín Mòniáng; Pe̍h-ōe-jī: Lîm Be̍k-niû / Lîm Bia̍k-niû / Lîm Be̍k-niô͘), a shamaness from Fujian who is said to have lived in the late 10th century. After her death, she became revered as a tutelary deity of Chinese seafarers, including fishermen and sailors.
Her worship spread throughout China's coastal regions and overseas Chinese communities throughout Southeast Asia, where some Mazuist temples are affiliated with famous Taiwanese temples. Traditionally, Mazu was believed to roam the seas, safeguarding her devotees through miraculous interventions. She is now generally regarded by her believers as a powerful and benevolent Queen of Heaven.
