The Johnston Laboratories at the University of Liverpool in Liverpool, England, performed a variety of pathology and medical research during the 20th century. They are now located in the Johnston Building. The Laboratories were founded by early University benefactor and ship owner William Johnston and formally opened on 9 May 1903. Research activities of the Laboratories were documented in the Thompson Yates and Johnston Laboratories Report by the University of Liverpool Press. During the 1900s and 1910s the Liverpool School of Tropical Medicine was partly housed in the laboratories.
