In Roman mythology, Concordia was the goddess of agreement, understanding, and marital harmony. Her oldest temple was on the Forum Romanum. It was built in 367 BC by Marcus Furius Camillus. The Roman Senate often met there.

In art, Concordia was depicted sitting, wearing a long cloak and holding onto a sacrificial bowl and a cornucopia. Sometimes, she is shown standing between two members of the Royal House shaking hands.

Her opposite is Discordia.
