McCarthy, Collings & Co. was an architectural partnership formed by Thomas Ignatius McCarthy (1880-1951) and Harry Collings (1883-1959) in Coalville, Leicestershire, England in c.1911. Their office was located in Central Chambers, Coalville from 1911 to 1936. McCarthy and Collings remained in partnership until at least 1939. The practice may have been dissolved that year following the outbreak of World War Two.
