Chiajna () is a commune in the south-west of Ilfov County, Muntenia, Romania, immediately west of the capital, Bucharest. It is composed of three villages: Chiajna, Dudu, and RoÃÂu.
The mayor of Chiajna is currently Mircea Minea (Social Democratic Party).
Chiajna is a Romanian female name, being a feminine version of "cneaz" (Knyaz).
In one version Chiajna was named after the wife of Cernica ÃÂtirbey, a Wallachian vornic who owned the area where people from CernavodÃÂ settled and founded the village.
Another story says that Lady Chiajna ( 1525âÂÂ1588, Istanbul) was the daughter of Petru RareÃÂ, the voievod of Moldavia, an illegitimate child of ÃÂtefan cel Mare. Lady Chiajna was the wife of Wallachian prince Mircea V Ciobanul. In Romanian literature (e.g., the novella Doamna Chiajna, published in 1860 by author Alexandru Odobescu), she is a famous and frightening female character, similar to Lady Macbeth.
Chiajna is one of the fastest growing localities in Romania. Its population increased from 14,259 people at the 2011 census to 43,584 people according to the 2021 census.
The commune is home to the Lady Chiajna Technological High School, which has a Tourism and Public Alimentation specialization and a Sports specialization.
The commune is host to the football team Concordia Chiajna. The team is in Liga II, and plays its home matches on Stadionul Concordia. The Concordia Chiajna basketball team was founded in 1957 and dissolved in 2013.
Since the 2010s, Chiajna has been the site of new residential developments collectively known as "Militari Residence", which have become notorious for their poor urban planning and construction practices.
