A photographer of the French news agency Agence France-Presse (AFP) was abducted by masked men from outside the agency's office here, media reports said.
According to witnesses, Jaime Razuri was forced to get into a car on Monday that sped off.
The Peruvian national had arrived in Gaza a week earlier. No group has claimed responsibility for the kidnapping.
Foreigners have been frequent targets of abductions, usually being freed unhurt after a period of days or weeks.
