The incorporation of strong electronic and magnetic correlations in 2D vdW metals remains a sought-after platform to enable control of emergent quantum phases and to achieve more theoretically tractable microscopic models of complex materials. To date, however, there is limited success in the discovery of such metallic vdW platforms, and f-electron monolayers remain out of reach. Here, we demonstrate that strongly correlated \u03b2\u2013uranium tritelluride (\u03b2-UTe\n                    <jats:sub>3<\/jats:sub>\n                    ) can be exfoliated to the monolayer limit. Unexpectedly, \u03b2-UTe\n                    <jats:sub>3<\/jats:sub>\n                    remains ferromagnetic in this limit with an enhanced ordering temperature of 35 kelvin, a factor of two larger than its bulk counterpart. Our work establishes \u03b2-UTe\n                    <jats:sub>3<\/jats:sub>\n                    as a materials platform for investigating and modeling correlated behavior in the monolayer limit and opens numerous avenues for quantum control with, e.g., strain engineering.\n
