Hurricane Hilary was a large and intense Pacific hurricane in August 2023 that brought torrential rainfall and gusty winds to the Pacific Coast of Mexico along the Baja California peninsula, and the Southwestern United States, resulting in widespread flooding and mudslides to the region. The hurricane was the eighth named storm, sixth hurricane, and fourth major hurricane of the active and highly destructive 2023 Pacific hurricane season.^{[nb 1]} Hilary originated from a tropical wave south of Mexico on August 16, and strengthened into a hurricane a day later while paralleling the southwest coast of Mexico. The system underwent rapid intensification, reaching maximum sustained winds of 140 mph (220 km/h) and a central pressure of 940 mbar (27.76 inHg) on August 18, making it a Category 4 on the Saffir-Simpson scale. After environmental conditions became unfavorable, Hilary weakened as it approached land, making landfall on August 20 as a tropical storm in San Quintín along the western Baja California peninsula. Hilary became a post-tropical cyclone over land, before being absorbed into a new non-tropical low-pressure area early on August 21.

The threat from Hurricane Hilary prompted widespread and varied preparations. In Mexico, thousands of people evacuated to shelters as ports closed along the coast. In anticipation of "catastrophic and life-threatening flooding", the National Hurricane Center (NHC) issued its first-ever tropical storm warning for Southern California, extending from the Mexico–United States border to just north of Los Angeles.
