HMS Danae was a Leander-class frigate of the Royal Navy. She was, like the rest of the class, named after a figure of mythology. Danae was built by Devonport Dockyard. She was launched on 31 October 1965 and commissioned on 10 October 1967.

The Leander-class, or Type 12I (Improved) frigates, comprising twenty-six vessels, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular BBC television drama series Warship. The Leander silhouette became synonymous with the Royal Navy through the 1960s until the 1980s.
