A radio-frequency front-end circuit includes a first filter that has a first pass band and is connected to an antenna common terminal, a second filter that has a second pass band and is connected to the antenna common terminal, a switch that includes a common terminal and selection terminals, the common terminal being connected to the first filter, and a third filter that is connected to one of the selection terminals and is disposed between the switch and an input/output terminal. A reflection coefficient of the first filter alone in the second pass band viewed from the antenna common terminal is larger than a reflection coefficient of the third filter alone in the second pass band viewed from the antenna common terminal.
