There are 60+ active Ubuntu-based distros, even though the exact number is challenging to mention as there exist many unofficial modifications of Ubuntu. This abundance makes it difficult to track all of them accurately. Some of the well-known ones include Zorin OS, Pop!_OS, Linux Mint, KDE Neon, Kubuntu, Elementary OS, Lubuntu, Xubuntu, Ubuntu Budgie, and Ubuntu Mate, among others.
