Pichincha is a province of Ecuador located in the northern Sierra region; its capital and largest city is Quito. It is bordered by Imbabura and Esmeraldas to the north, Cotopaxi and Santo Domingo de los Tsáchilas to the south, Napo and Sucumbíos to the east, and Esmeraldas and Santo Domingo de los Tsáchilas to the west.
Prior to 2008, the canton Santo Domingo de los Colorados was part of the Pichincha Province. It has since become its own province, Santo Domingo de los Tsáchilas.
The province is home to many rose plantations, which make up the bulk of Ecuador’s floriculture industry
