Bayside is an unincorporated community 2.25 miles (3.6 km) south-southeast of Arcata,[3] at an elevation of 33 feet (10 m) in Humboldt County, California.

Today, Bayside provides Arcata a buffer from Eureka's northward expansion along US Route 101 and the area, with the exception of some business and public buildings, is largely rural, with homes and small ranches dotting the landscape.

Prior to white settlement in the 1850s Wiyot Indian villages dotted the area and the present main roads were established trails.

[12]: 21 William Carson's first logging claim was in Bayside, and he brought in workers from New Brunswick, Canada who settled in the area.

The original Jacoby Creek School was built in 1903 and added to the National Register of Historic Places in 1985.
