Sycamore (formerly, Loch-loch) is a former settlement in Colusa County, California.

It lies near the mouth of Sycamore Slough, at an elevation of 49 feet (15 m).

Sycamore was a farming community in the late nineteenth century and once had a mill, church, school, and a nearby station on the Northern Electric railway branch to Colusa.
