Cidade Ocidental is a municipality located in central Goiás state, Brazil.
It is bordered on the north by the Federal District, on the south by Luziânia, on the east by Cristalina and Luziânia, and on the west by Luziânia and Valparaíso de Goiás.
The municipality has a tropical with altitude climate with temperature variations between 18 °C and 28 °C. The vegetation is typical of the cerrado with short and twisted trees, with some pockets of tropical tree growth. The main rivers are the São Bartolomeu, Saia Velha and Mesquita.
Cidade Ocidental is the case of a community formed by the need to give inexpensive housing to the lower and lower-middle sectors in the Federal District. With no more housing available inside the District new communities have sprung up in neighboring Goiás. The city, with poor infrastructure and serious budgetary problems, makes up an urban sprawl extending for more than 40 km. from Luziânia to the limit of the Federal District, where rules for construction are more rigid. A neighboring city created under the same conditions is Valparaíso de Goiás.
Livestock processing, services, small industries, government employment and modest agriculture are the main sources of income for the municipality. The presence of packing houses and slaughter houses has created a good number of direct and indirect jobs. In the agricultural sector there was modest production of rice, coffee, sugarcane, beans, oranges, lemons, manioc and tangerines.
