Animal ethics is the branch of ethics concerned with the moral status of non-human animals and the obligations of humans toward them. It examines which beings deserve moral consideration, what kinds of treatment are permissible, and how social, legal, and scientific practices should be shaped. The field draws on moral philosophy and applied ethics to address issues across research, farming, entertainment, conservation, and companion animal care.

Key theoretical approaches include utilitarianism, which judges actions by their consequences for animal welfare; deontological and rights-based theories, which argue that animals possess inherent rights or dignities that constrain use and harm. In contrast, virtue ethics emphasizes character and humane conduct. A practical framework is the 3Rs principle—replacement, reduction, refinement—aimed at minimizing animal use and suffering in research. Regulations and oversight bodies, such as institutional animal care and use committees, govern compliance in many countries. Legal instruments vary by region, with comprehensive animal-welfare laws in parts of Europe and North America, and different standards elsewhere.

Ethical debates focus on the morality of animal testing, factory farming, hunting, and entertainment, weighing scientific or social benefits against harms. Critics advocate greater emphasis on alternatives, animal rights, and shifting cultural norms toward empathy and welfare. The field informs policy, industry practice, and research methodology, while remaining contested and evolving as scientific knowledge and public values change.
