Haj Habib Ibrahim Abdullah lost his life when Bahraini security forces attacked anti-regime protesters in Malkiya village near the capital Manama.
His nine-year-old grandson was injured in the incident and has been sent abroad for treatment
The funeral procession of the victim is due to be held on Sunday.
The Bahraini uprising began in February 2011. Manama promptly launched a brutal crackdown on peaceful protests, calling in Saudi-led Arab forces from neighboring states.
Dozens of Bahrainis have lost their lives since the revolution began in the Persian Gulf Kingdom.
Bahraini protesters say they will continue holding anti-regime demonstrations until their demand for the establishment of a democratically elected government is met.
