The Yuba City Bears were a summer collegiate baseball team based in Marysville, California, in the United States and representing Yuba City, California.

They were a member of the Great West League, having been established in 2017, and had played their home games at Colusa Casino Stadium adjacent to Ellis Lake, in Marysville.

They had shared the facilities with the Yuba-Sutter Gold Sox,[1] but have since folded their GWL operations.

[2] They were founded to bring back a natural rivalry with the Marysville Gold Sox as the original Bears and Marysville Giants competed during that time.

[3] On November 7, 2017, the GWL announced that the Bears were not going to play in 2018 and have since been replaced by the San Francisco Seals.
