J R Hamilton was an architect from Gloucester, England, active in the mid-19th century. He is especially noted for his cemetery designs, which he often carried out with J M Medland.
Together, Hamilton and Medland designed the buildings for the Anglican Warstone Lane Cemetery in Birmingham (opened 1848), won the competition for the Plymouth Cemetery, 1848, and designed the layout and buildings of the Welford Road Cemetery in Leicester (opened 1849).
