We detail the occurrence of a Slate-throated Redstart (Myioborus miniatus) in an urban park in San Francisco from 29 July to 16 September 2024, establishing the first record for California and the northernmost for the species. The bird showed characters of the northern subspecies, M. m. miniatus. It may have reached this site as a late spring overshoot or possibly via a molt migration. This represents the 47th species of wood-warbler (Parulidae) recorded in California, and—remarkably—the 46th for San Francisco County.
