The man was killed by unknown assailants in a tailor's shop in Benghazi's Al-Berka district, where he was working.
There have been a number of recent murders and kidnappings of Egyptian expatriate workers in Libya in recent months, as rival militias and a toothless central government struggle for control.
In August, Islamist militants carried out a summary execution of an Egyptian citizen inside a football stadium in Derna.
The Egyptian foreign ministry has already issued several travel warnings to its citizens to avoid the conflict-ridden territory.
Egypt also organised multiple flights to repatriate several thousand Egyptians who had fled from Libya to Tunisia after escalating violence in July.
According to the International Organisation for Migration, between 330,000 and 1.5 million Egyptians worked in Libya until an uprising toppled Muammar Gaddafi in 2011. It is unclear how many Egyptian workers remain in Libya at present.
In August, the Egyptian and Libyan foreign ministers announced an Egyptian- sponsored plan to disarm Libya's militants and bring stability to the country.
