The Iloilo Strait is a strait in the Philippines that separates the islands of Panay and Guimaras in the Visayas, and connects the Panay Gulf with the Guimaras Strait. It is the location of the Port of Iloilo, the third busiest of the ports in the Philippines in number of ships. Iloilo City on Panay is the major city located on the strait with Buenavista and Jordan, both on Guimaras, immediately across the strait from the city. The Iloilo River empties into the strait.
Pumpboat ferries cross every few minutes from Iloilo City to Guimaras and vice versa. Ships doing business with the Port of Iloilo often moor in the strait.
The Port of Iloilo was opened for international trade in 1855 and the coming of British Vice-consul Nicholas Loney, a year later, led to the fast development of the sugar industry in the region.
