Louisa Jane Bryer (Chinese: 布萊爾女士 [2]) (November 17, 1867 – December 25, 1958) was an English Protestant Christian missionary to China.

[3] Bryer spent 28 years in China (1891–1917; 1924–1926) and in 1896 translated the entire New Testament into the Northern Min language[4] by adopting the Kienning Colloquial Romanized writing system.

She arrived at the Ciong-Bau (上堡) village Mission Station near Kienning, the capital of the Northwest Prefecture of Fujian Province where she worked alongside other Church of England Zenana Missionary Society missionaries.

It was during this period when Bryer first began learning the local Northern Min language and, in order to facilitate the missionary work, developed the Kienning Colloquial Romanized alphabet.

Bryer emigrated to Canada in 1938 where she spent the remaining two decades of her life with her brother and sister-in-law in New Westminster, British Columbia.
