The first Europeans to see Point Roberts were members of the 1791 expedition of Francisco de Eliza.
The maps produced from Eliza's explorations depicted Point Roberts as "Isla de Cepeda" or "Isla de Zepeda."
In 1792 the British expedition of George Vancouver and the Spanish expedition of Dionisio Alcalá Galiano encountered one another near Point Roberts.
In the morning of June 13, 1792, the two ships under Galiano sailed into Boundary Bay and verified Point Roberts was not an island, which was thus renamed Punta Cepeda.
They then sailed around Point Roberts and immediately encountered HMS Chatham, the second ship of Vancouver's expedition.
The two parties made contact and agreed to share information and work together in mapping the Strait of Georgia.

Point Roberts acquired its present name from Vancouver, who named it after his friend Henry Roberts, who had originally been given command of the expedition.
 Point Roberts assumed its present political status in 1846, when the Oregon Treaty extended the 49th parallel as the boundary between U.S. and British territory from the Rocky Mountains to Georgia Strait.
