Hillside Elementary School, Public elementary school in Berkeley, California.

Hillside Elementary School is a 50,302-square-foot former public elementary school at 1581 Le Roy Avenue in the Berkeley hills, bounded by Le Roy Avenue, Buena Vista Way and La Loma Avenue. The 1925 building by architect Walter H. Ratcliff has a 1964–65 wing, and its playground has long served residents as a de facto neighborhood park.

The original building from 1901 was destroyed in the 1923 Berkeley fire. The current structure was designed and built by architect Walter H. Ratcliff in 1925.

The building shows the style of early 20th-century California schools and reflects how the community valued education at that time. You can see this in its careful design and how it fits into the neighborhood.

The site is accessible by public paths and offers open areas visible during the day. The playground and pathways let visitors walk through the property and see how it connects to the surrounding neighborhood.

The German International School of Silicon Valley occupied the building from August 2012 until December 2016, when it closed due to unmet seismic retrofit needs. In 2018 the school sold the property to Finnish entrepreneur Samuli Seppälä, who plans to redevelop it into a home and artists' colony. The playground has long been used by neighbors as a de facto park, and Seppälä said it would be kept open voluntarily.
