A radio frequency module and a communication device capable of reducing a mounting substrate size. The radio frequency module includes a mounting substrate, a first filter, and a second filter. The mounting substrate has a first main surface and a second main surface that are on opposite sides of the mounting substrate. The first filter is provided on the first main surface and allows a first receiving signal in a first frequency band to pass through. The second filter is stacked on the first filter and allows a second receiving signal in a second frequency band different from the first frequency band to pass through.
