A mistress is a relatively long-term female lover and companion who is not married to her partner, especially when her partner is married to someone else.

Generally, the relationship is stable and at least semi-permanent, but the couple does not live together openly and the relationship is usually, but not always, secret. There is often also the implication that the mistress is sometimes “kept" – i.e. that her lover is contributing to her living expenses.[1][2]

The term "mistress" was originally used as a neutral feminine counterpart to "mister" or "master".[1]
