What is a group of giraffes called?

There isn't a formally recognized name for a group of giraffes like there is for some other animals (e.g., a pride of lions, a flock of sheep). However, several terms are used informally and playfully. These include:

• A tower of giraffes: This is perhaps the most common and evocative term, reflecting their height and the way they often stand close together.
• A herd of giraffes: While "herd" is generally applied to many grazing animals, it's perfectly acceptable and understandable when referring to a group of giraffes.
• A journey of giraffes: This is a more poetic and less frequently used term, but it captures the image of giraffes' long migrations.

Ultimately, any of these terms would be understood, though "tower" or "herd" are the most widely accepted. There's no single "correct" answer.
