Taylor Mountain, Summit in Sonoma County, California.

Taylor Mountain is a 1,406-foot summit at the northern end of the Sonoma Mountains, about 5.6 km south of Santa Rosa. Its east flank drains to Matanzas Creek and its west flank to Five Creek, both in the Laguna de Santa Rosa basin. The 1,100-acre Taylor Mountain Open Space Preserve covers the mountain with dirt trails for hikers.

John Shackleford Taylor, a Gold Rush pioneer, established a dairy farm and vineyard on the mountain slopes during the 1850s, and the geographic feature later took his name. The site has evolved from agricultural use to its current state as a public land area.

The mountain defines the boundary between two wine appellations, with its western slopes belonging to Sonoma Coast and eastern slopes to Sonoma Valley wine regions.

Trail access is from a parking lot near the eastern end of Kawana Terrace, off Kawana Springs Road east of Santa Rosa Avenue and Petaluma Hill Road. A second trailhead on Petaluma Hill Road, south of Yolanda Avenue, opened in 2015 with picnic tables and horse-trailer parking; a 1.2-mile trail links it to the rest of the park. Day use costs $7 per vehicle and the park is open from 8 AM to sunset. Dogs must be licensed and kept on leashes no longer than 6 feet.

Taylor Mountain marks part of the boundary between two federal grape-growing regions: grapes from its western slopes fall in the Sonoma Coast AVA, those from its eastern slopes in the Sonoma Valley AVA. The peak is visible from Sonoma Mountain, Bennett Valley, the Santa Rosa Plain and as far north as the Alexander Valley.
