A monologist, or interchangeably monologuist, is a solo artist who recites or gives dramatic readings from a monologue, soliloquy, poetry, or work of literature, for the entertainment of an audience. The term can also refer to a person who monopolizes a conversation; and, in an obsolete sense, could describe a bird with an unchanging, repetitive song.

In theatre, a monologue is a speech presented by a single character, most often to express their thoughts aloud, though sometimes also to directly address another character or the audience. Monologues are common across the range of dramatic media, as well as in non-dramatic media such as poetry. Monologues share much in common with several other literary devices including soliloquies, apostrophes, and asides. There are, however, distinctions between each of these devices.
