Crucecita is a town of the Avellaneda Partido in Buenos Aires Province, Argentina.

The town is named for the Arroyo de la Crucecita (Crossing Stream) encountered by a 1580 expedition led by Captain Juan de Garay, the founder of modern-day Buenos Aires.

The Real Consulado de Buenos Aires ordered a pontoon bridge built over the stream in 1810, and much of the surrounding land later belonged to the Ximenez family.

A wave of immigration in Argentina after 1880 led to the southward expansion of the Buenos Aires metro area part Avellaneda, and the first lots in Crucecita were sold to homesteaders in 1887.

Presidente Bartolomé Mitre Avenue connects the suburb to Avellaneda, to the north, and Sarandí, to the south.
