The Anti-Harassment Tools (AHT) team was a Wikimedia Foundation team focused on IP Editing: Privacy Enhancement and Abuse Mitigation, sometimes referred to as IP Masking, later renamed into Temporary Accounts.

Previously, AHT did technical work in support of the Community health initiative that aim was to reduce the level of harassment and disruptive behavior on wikis.

The team was formed in 2018. In 2023, it was merged with Trust and Safety Tools to form Trust and Safety Product, which in 2025 was merged with Product Security to form Product Safety and Integrity.
