Santana Filomena Ceirico Camilo "Cyriaco" Dias (born 16 March 1937) is an Indian actor, playwright, theatre director, singer, freedom fighter, and social worker known for his work in Konkani films and tiatr productions.

During this period, Dias assumed the guise of a Hindu individual named Shembu Canconkar, donning traditional attire such as a dhoti.

[3] Dias embarked on his theatrical career in his youth by joining a cultural club led by Seby Coutinho, Rico Rod, and Vincent Semedo.

However, he achieved success with his first staged social drama, Zigzigta Titleim Bangar Nhoim (All That Glitters is Not Gold) in 1956, solidifying his position as a rising star.

[5] The same year he participated in the productions Kitem Ho Sounsar (What sort of world is this) and Chepekar Cunhado (Hat wearer Brother-in-law).

Despite his retirement from Bahrain, Dias has maintained his passion for the stage and intends to complete his unfinished work in the Konkani theater.

This was evident when Dias spoke about Rod's character during a condolence gathering held at the Black Box in Ravindra Bhavan, Margao, to pay tribute to the late playwright and director.

[13] Furthermore, his role in the Konkani film Amchem Noxib led to a felicitation by former Goa Legislative Assembly speaker Tomazinho Cardozo at the Thomas Stephens Konknni Kendr (TSKK).
