Opposition to hunting is espoused by people or groups who object to the practice of hunting, often seeking anti-hunting legislation and sometimes taking on acts of civil disobedience, such as hunt sabotage.

Furthermore, they showed the UK's anti-hunting movement was itself only part of a wider, grassroots opposition to hunting in the UK. The Burns Inquiry reported that:
