The Animal Health Trust (AHT) was a large national independent charity in the United Kingdom, employing 200 scientists, veterinarians and support workers.

Its objectives were to study and cure diseases in pets (horses, dogs and cats), and research and postgraduate education in veterinary medicine.

Based in Newmarket in Suffolk, it was a registered charity under English law[8] and received no government funding.

[3] One of its first major donors was Annie Henrietta Yule, co-owner of Hanstead Stud, who offered the Trust the use of her Newmarket stable, Balaton Lodge.

Following fundraising difficulties and issues aggravated by the COVID-19 pandemic, the Animal Health Trust entered liquidation on 31 July 2020 with an auction for medical equipment in August 2020.
