Online abuse is any type of abuse that happens on the internet. It can happen across any device that's connected to the web, like computers, tablets and mobile phones. And it can happen anywhere online, including:

• social media
• text messages and messaging apps
• emails
• online chats
• online gaming
• live-streaming sites.

Children can be at risk of online abuse from people they know or from strangers. It might be part of other abuse which is taking place offline, like bullying or grooming. Or the abuse might only happen online.
