The Balliol-Trinity Laboratories in Oxford, England, was an early chemistry laboratory at the University of Oxford.^[2] The laboratory was located between Balliol College and Trinity College, hence the name.^[3][4] It was especially known for physical chemistry.

Chemistry was first recognized as a separate discipline at Oxford University in the 19th century. From 1855, a chemistry laboratory existed in a basement at Balliol College.^[2] In 1879, Balliol and Trinity agreed to have a laboratory at the boundary of the two colleges. The laboratory became the strongest of the Oxford college research institutions in chemistry.^[5] It remained in operation until the Second World War when a new Physical Chemistry Laboratory (PCL) was constructed by Oxford University in the Science Area.^[2]
