The $e^+e^-\\to\\eta\\pi^0\\gamma$ cross section is measured for the first time. It is shown that the dominant mechanism of this reaction is the transition through the $\\omega\\eta$ intermediate state. The measured cross section of the subprocess $e^+e^-\\to\\omega\\eta\\to\\eta\\pi^0\\gamma$ is consistent with previous measurements in the $e^+e^-\\to\\pi^+\\pi^-\\pi^0\\eta$ mode.
