Tim McGraw and Faith Hill have been married for 16 years, while Blake Shelton and Miranda Lambert are a young couple, having said "I do" just under a year ago. Garth Brooks and Trisha Yearwood will celebrate seven years this December, but even those three famed pairs put together don't equal the all-time most famous country couple. Johnny Cash and June Carter Cash were married for 45 years before her death in 2003.

Which country couple is your favorite? We've also added Vince Gill and his wife Amy Grant to this readers poll, and as always you're encouraged to chime in with those we missed in the comments section below. Use your own set of criteria to decide -- maybe it's the couple that makes the best music together, or perhaps it's just the couple who is the cutest.
