The Eastside Community Center, formerly the Catholic Holy Cross Church, is an historic building in Batavia, Illinois.

It was built in 1897 to serve the Holy Cross congregation of Batavia, many of whom were Irish immigrants who came to work in local quarries.

The building operated as a church until the 1990s, when the property was transferred to the Batavia Park District.

The Catholics took over a vacant church building for their services in 1870 and became the Holy Cross congregation.

On April 27, 1996, the old building was transferred to the Batavia Park District and serves as the assembly hall of the Eastside Community Center.

The building is on a 165 by 264 foot (50 by 80 m) lot in a residential neighborhood three blocks east of the Fox River.
