​AGUADILLA, a town and port near the northern extremity of the W. coast of Porto Rico. Pop. (1899) 6425. It has a fairly good and safe anchorage, and is the commercial outlet for a very fertile agricultural district. The town is attractively situated and well built, and is connected by railway with Mayaguez, 20 m. distant, and also with Ponce and San Juan. The neighbouring district produces sugar-cane, tobacco, cattle, cocoanuts, oranges and lemons. The bay is supposed to have been first visited by Columbus (November 1493), though the town was not founded until 1775.
