Shire Christian School is an independent non-denominational Christian co-educational early learning, primary and secondary day school, located in Barden Ridge, a suburb in the Sutherland Shire area of Sydney, New South Wales, Australia. The school was founded as Sutherland Shire Christian School in 1977 by a group of local parents who felt a calling to provide their children with an environment in which to gain an education taught from a Christian perspective. They believed that these features were not to be seen in a public state school; because of this the school upholds a strong Christian ethos that influences most parts of school life.

In 2015 the school jumped nearly 200 places and ranked 65th in the State in NSW Higher School Certificate (HSC) results.

The school consists of one large campus in the southern suburb of Barden Ridge, and this campus facilitates the two sections of the school:

• A high school (Years 7 to 12) and
• A junior school (Preschool to Year 6).

In 2016, the school's name was changed to Shire Christian School.

The School Association was formally founded in 1969 by several Christian families who wished to have a Christian environment for their children to grow and mature in. The school officially began in 1977 under the name Sutherland Shire Christian School and the Sutherland Shire Christian School Association Ltd was created two years later in 1979.

School classes were originally housed in several locations (such as local church halls) before the purchase of several hectares of farm land in the southern Sydney suburb of Barden Ridge, in 1981, where the school has continued to develop since.
