The Frank Rankine Residence and the Henry Rankine Residence are an adjoining pair of brick residences in Saint John. On the left side at 210 Germain Street is the Frank Rankine Residence, which has a black door, while the Henry Rankine Residence on the right is at 212 Germain Street and features a brown door. The twin residences are good examples of the sort of brick Italianate architecture that had exploded in popularity following the Great Saint John Fire of 1877. They are currently a part of the Trinity Royal Preservation Area, a historic district where many of Saint John's heritage buildings can be found, and continue to be used as private residences.

The residences were built for and occupied by brothers Henry and Frank Rankine. The brothers played an important role in the business world of Saint John. Though exact details differ between the sources, it is known that their grandfather, Thomas Rankine Sr., founded his biscuit-making business, T. Rankine and Sons, in 1826, a few years after coming to Canada from Scotland. His sons, Thomas A. and Alexander, joined him, with the former being Henry and Frank Rankine's father. After the death of Thomas A. in 1907, older brother Henry became president of the firm, while younger brother Frank assumed the position of vice president. Shortly afterwards, the business was incorporated as a joint stock company and quickly proved successful. Their best-known creation was a circular design with a floral pattern in the centre that was turned into a cookie mould that was used by the Girl Guides of Canada. This motif was later copied in the cast iron fence and gate in front of the Rankine properties.

Henry left 212 Germain Street after his retirement in 1920 (having given the position of president some time before to his other brother Allan, who in turn passed it onto Frank's son H. Fielding Rankine), while Frank Rankine remained in his residence until his death in 1922. In the present, the homes are a part of the Trinity Royal Preservation Area, and they are still used as private residences.
