José Domingos de Morais (12 February 1941 – 23 July 2013), better known as Dominguinhos, was a Brazilian composer, accordionist and singer.

During his lifetime, Dominguinhos received various prizes and awards, including the Latin Grammy in 2002 for his album "Chegando de mansinho".

Dominguinhos became interested in music at an early age, starting to play accordion at six years of age, when he received a small eight-bass-accordion and started to play on fairs and in front of hotels, to earn some money with his two brothers, forming the trio "Os Três Pinguins" (The Three Penguins).

Dominguinhos went only in 1954, at age thirteen, together with his father and his two brothers, moving to the town of Nilópolis, near Rio de Janeiro.

He was later transferred to the Syrian-Lebanese Hospital, in São Paulo, where his coma was described as permanent and doctors said there were no hopes he will return and wake up again.
