Lascano is a small town in the Rocha Department of southeastern Uruguay.

A village was first founded in the fields of ranchers Don Francisco Fernández and Don Francisco Lascano, by decree of 10 February 1876.

The estates were situated on what was called until then "Partido de las Tres Islas".

Although Don Lascano had a much smaller portion of land, the village used the name as it was on the signed official papers.

[1] On 4 July 1908, its status was elevated to "Villa" (town) by the Act of Ley N° 3.304[2] and on 3 November 1952 to "Ciudad" (city) by the Act of Ley N° 11.874.
