An extremely well-suited pairing of people or things; a match that will result in a particularly positive or successful outcome. Mike and Timothy are a match made in heaven! I can't think of two people better suited to marry one another. The new wide receiver and the team's veteran quarterback have proved to be a match made in heaven on the field.

A very happy marriage or partnership. When Kelly and Julie partnered up and opened their restaurant, it was a match made in heaven. Cindy and Mark look so happy together. That's a match made in heaven.
