Arnele Avenue station is a San Diego Trolley station served by the Copper Line in the San Diego suburb of El Cajon, California. The station serves the surrounding residential community, the Parkway Plaza shopping mall, and other commercial properties in the area. The station also has a small park and ride lot.

Arnele Avenue opened as part of the fourth and final segment of the East Line (now Orange Line) on July 26, 1995, which extended the line from El Cajon to Santee. Green Line service began in July 2005, when the Orange Line was truncated to Gillespie Field. Following the September 2012 system redesign, Orange Line trains stopped serving this station and began terminating at El Cajon. However, the line's eastern terminus was once again extended on April 30, 2018, this time to Arnele Avenue. On Sepetember 29, 2024, the station became part of the Copper Line, and both the Green and Orange lines were truncated back to El Cajon.
