La Honda (Spanish for "The Sling") is a census-designated place (CDP) in southern San Mateo County, California, United States. The population was 979 at the 2020 census. It is located in the Santa Cruz Mountains between the Santa Clara Valley and California's Pacific coast. La Honda is near the La Honda Creek Open Space Preserve and State Route 84 on the ocean side of the Coastal Range.

The ZIP Code for La Honda is 94020 and the area code is 650. Land-line numbers in the La Honda telephone exchange follow the pattern 747-xxxx while wired telephones in and around the Middleton Tract (along Portola State Park Road) work out of the Los Altos exchange with 94x-xxxx numbers. Per the U.S. Geological Survey, Lahonda is a historic variant of the modern spelling.

According to the United States Census Bureau, the CDP covers an area of 4.3 square miles (11.0 km), 99.65% of it land, and 0.35% of it water.

La Honda is home to diverse habitats, from cool, moist forests of coast redwood and coast Douglas fir, to mixed woodland, chaparral, and grassy hillsides.

This region experiences warm (but not hot) and dry summers, with no average monthly temperatures above 71.6 °F (22.0 °C). According to the Köppen Climate Classification system, La Honda has a warm-summer Mediterranean climate, abbreviated "Csb" on climate maps. In addition, like much of California, the town receives most of its rain between November and April. Due to El Niño, the region sometimes receives heavy winter rains, making it vulnerable to landslides. Scenic Drive, a local road, has seen three landslides since 1998. With elevations ranging from about 300 feet where La Honda Creek meets Alpine Creek, to more than 1200 feet in the hills, the weather may vary between the town's hillsides and valleys. Sometimes the marine layer is too low to reach the hills, leaving the lower elevations foggy or overcast while the mountains enjoy clearer weather. On some winter nights, similar thermal inversions trap cold air in the valleys, leading to frost, with higher elevations remaining generally milder. These same weather patterns are at play in much of the coast-facing Santa Cruz Mountains.

The creek that runs through the town is listed as Arroyo Ondo on several diseños on the Mexican land grants and as Arroyo Hondo on the 1856 Rancho Cañada de Raymundo map. Hondo is Spanish for 'deep'. The post office was listed as La Honda in 1880 and revised to Lahonda after 1895. The name was restored in 1905 owing to Z. S. Eldredge's efforts.

In 1862 John Howell Sears purchased 400 acres and settled in La Honda after his prior residence in Searsville was sold to the water company due to the decline of lumber and flooding issues. The early days of La Honda were built around the lumber industry and the Old Store at La Honda was one of the earliest buildings.

Ken Kesey, the author of One Flew Over the Cuckoo's Nest (pages of which were written all over the restroom wall of his La Honda residence) and other books, owned a home in La Honda, which served as the base of operations for The Merry Pranksters where they used LSD and other drugs. The escapades of Kesey and the Merry Pranksters are documented in Tom Wolfe's The Electric Kool-Aid Acid Test, which describes the wildly painted school bus, 'Furthur', driven by Neal Cassady, who had been the hyperkinetic driver in Jack Kerouac's On the Road.

The La Honda house where Kesey's adventures became famous—one mile (1.6 km) west of Apple Jack's Inn—has been faithfully restored after years of neglect and a near-catastrophic flood in 1998.

The town has a single school, La Honda Elementary, located within the La Honda-Pescadero Unified School District.

The town hosts the La Honda Fair & Music Festival every June, and holds an annual Fourth of July picnic at Play Bowl.
