The piglets, which have been revealed as two girls and one boy, have been called Hedwig, Nagini and Aragog in tribute to some of the animals at the famous school of witchcraft and wizardry.
The trio arrived to mum Tamzin (7) and dad Magnum (10) on 9 June after a six month pregnancy.
Now, standing at only 20cm tall, the youngsters have taken their very first playful steps outside having spent a few weeks in their den bonding with mum.
Kim Wood, assistant team manager at the zoo, said:
Our Harry Potter naming theme is just a bit of fun for the keepers. But, having been successful at breeding warthogs in recent years, we have to be more and more creative with the names we choose. Previously we’ve had the likes of Harry, Ron and Hermione and so this time around we’ve named our latest piglets after some of the animals featured in the books.
These three little youngsters will no doubt be causing mischief and keeping mum very busy over the next few weeks as they form those vital early bonds. This is Tamzin’s third litter and so she’s a very experienced mum and is doing a brilliant job of caring for her new arrivals.
It’s great to see them all outside exploring for the first time – they’re a very confident bunch.
Native to Africa, warthogs are an iconic species known for their curving tusks and wart-like growths on the sides of their heads. They are under pressure in some parts of the continent because of drought and hunting which have already brought about some localised extinctions.
Chester Zoo’s latest warthog trio will now join a carefully coordinated European breeding programme for the species.
