The yet unnamed baby boy was born to mother, Kwanza, and father, Gugas, earlier this month.
New dad Gugas, the zoo's silverback gorilla, was born in the wild - but his parents were killed when he was young. It is believed they were targeted for bushmeat.
Zoo manager, Mark Challis, explained: "Almost all apes are either endangered or critically endangered and some professionals have even predicted that all species of ape will be extinct within 30 years, showing the fragility of animal life in the modern world and the importance of zoos such as Belfast!
"In recent decades, gorilla populations have declined by more than 50 percent and this is predominantly due to threats caused by humans, including bushmeat trade, habitat destruction and viruses."
Zoo curator, Julie Mansell, highlighted that because Gugas was born in the wild, he is genetically very important to the European breeding programme.
"Because Gugas is so important, last year we decided to test his fertility. The results were less than promising and it was suspected that Gugas would never father any infants. You can therefore imagine the entire teams' delight when we discovered that Kwanza was pregnant with her little miracle!"
The silverback was found abandoned at Lisbon Zoo in Portugal after a circus there, who had taken him for their show, dumped him due to his ill-health.
Gugas arrived in Belfast Zoo in 1998, but it wasn't until over a decade later that his mating partner Kwanza arrived from France.
And it seems that zoo is having a bit of a 'miracle baby' boom. In 2012, Lucy was the first chimpanzee to be born at the zoo in 15 years and was swiftly followed by Pixie earlier this year.
The zoo has launched a competition to name their precious new arrival. You can vote for your favourite name by going to the Belfast Zoo website.
