A baby giraffe is called a calf. This name for the newborn or young form of an animal is applied to many quadruped land mammals, such as oxen and cow.
Baby giraffes are typically born at a height just under 2 meters and a weight of about 100 kilograms. Female giraffe calves tend to be slightly larger than males. Twin calves are relatively uncommon, but they have occurred in a few cases.
The use of the term "calf" to describe a young mammal is seemingly independent of geography, as it is used to categorize not only North American mammals like cows, but also African giraffes and African and Asian elephants.
