With the aim of interpreting anomalous lensing events with no suggestedmodels, we conducted a project of reinvestigating microlensing data in andbefore the 2019 season. In this work, we report a multi-planet systemOGLE-2019-BLG-0468L found from the project. The light curve of the lensingevent OGLE-2019-BLG-0468, which consists of three distinctive anomaly features,could not be explained by the usual binary-lens or binary-sourceinterpretation. We find a solution explaining all anomaly features with atriple-lens interpretation, in which the lens is composed of two planets andtheir host, making the lens the fourth multi-planet system securely found bymicrolensing. The two planets have masses $\sim 3.4~M_{\rm J}$ and $\sim10.2~M_{\rm J}$, and they are orbiting around a G-type star with a mass $\sim0.9~M_\odot$ and a distance $\sim 4.4$ kpc. The host of the planets is mostlikely responsible for the light of the baseline object, although thepossibility for the host to be a companion to the baseline object cannot beruled out.
