Calfaria was one of the many Baptist chapels in Llanelli, Carmarthenshire, Wales.

Established in 1881, the original chapel was a modest red-brick building which cost £500 and was opened in January 1882.^[1] Within seven years a new chapel was built, designed by George Morgan of Carmarthen.^[1] It flourished for over a century before closing in the early twenty-first century. The building is now derelict.

Founded in 1881, the first minister was James Griffiths, who moved to Calfaria, Aberdare in 1890.

Calfaria was much affected by the 1904-05 Religious Revival, during which a large number of prayer meetings were held. However, a prominent member was so overcome by the emotional impact of the Revival that he was removed to Carmarthen Asylum.^[2]
