Lucia Khambang was a Thai Roman Catholic nun belonging to the Lovers of the Holy Cross. Born in 1917, she joined her religious order at the age of 14. While serving as a teacher in Songkhon, she became a victim of government crackdowns targeting the Catholic community during the rule of Prime Minister Plaek Phibunsongkhram. In 1940, she was executed alongside several companions for her refusal to abandon her religious convictions, becoming one of the recognized Martyrs of Songkhon.
