East Lansdowne is a borough in Delaware County Pennsylvania, United States.

According to the United States Census Bureau, the borough has a total area of 0.206 square miles (0.53 km2), all land.

[1] East Lansdowne is located about approximately one-half mile west of Southwest Philadelphia and is surrounded by Upper Darby Township, namely the Stonehurst/Stonehurst Hills/69th Street and Fernwood neighborhoods.

Union Avenue to the west separates Lansdowne from Upper Darby, while the East Lansdowne border is near Hirst Avenue, leaving a one-block expanse of land that is part of Upper Darby Township.

It is the former railroad track that gives East Lansdowne borough's western boundary that vaguely ovoid shape.

William Penn School District serves East Lansdowne.

[6] Saint Cyril of Alexandria Catholic Elementary School (K-8), founded in September, 1929,[7] was moved to and combined with St. Philomena in nearby Lansdowne, PA in 2021[8] after a protracted battle to keep the school open.

In December, 2005 the archdiocese proposed closing it, but it remained open after community members, inspired by a child with cystic fibrosis who asked for the Make a Wish foundation to save his school, donated $200,000 to keep it open.

In 2012 the Roman Catholic Archdiocese of Philadelphia proposed closing it again,[9] intending to merge it into St. Andrew School of Upper Darby.

St. Cyril of Alexandria Church in East Lansdowne opened in June 1928.
