"Summer Rain" is a song written by Robbie Seidman and Maria Vidal, produced by Rick Nowels for Belinda Carlisle's third album Runaway Horses (1989). The song is about a man who goes away to war and leaves his wife, saying that nothing will change—they will be together forever and always. Although the conflict is unidentified, images in the video of a transport aircraft on an airfield and troops parachuting from transport aircraft suggest the man is an airborne soldier. The song is set in the present as his widow sings it, remembering the last time she saw him. It was released around the world in 1990 and was issued as a CD single, 7" single and a 12" single.

Carlisle's version had minor success on the charts reaching the top thirty in the United States and the UK, but was a bigger hit in Australia, where it reached the Top Ten. It was later covered by artists including Slinkee Minx, whose cover version of the song also reached the top ten in Australia.

Belinda Carlisle stated in May 2013 that this was her favorite of her own songs.

"Summer Rain" achieved moderate commercial success in North America, where it was released as the second single from Runaway Horses (1989). In January 1990, the song entered the Billboard Hot 100, the main US chart, at number 86. Within seven weeks of its release it peaked at number 30 and stayed at that position for two weeks. The single spent 13 weeks on the Billboard Hot 100, six of which were in the top 50. The single was Carlisle's second to last song to chart on the Billboard Hot 100. It also peaked at number 29 on the US Billboard Adult Contemporary, where it spent eight weeks on the chart.

In Australia, the song had the most commercial success, where it was released as the album's third single on March 19, 1990. In early April 1990, it debuted at number 42. Within two months of its release it peaked in the top ten where it stayed for five weeks. The song reached its peak at number six and remained there for three weeks, spending a total of sixteen weeks in the top fifty. The Australian Recording Industry Association awarded the single a gold certification for shipping 35,000 copies and became the fortieth highest-selling single in Australia for 1990.
