History
The tournament was first held circa 1900 and was organised by the Northern Counties Lawn Tennis Association section, part of the Pacific States Lawn Tennis Association. It was held at the Sacramento Lawn Tennis Club, Sacramento, California, United States when it only staged a men's doubles event known as the Northern California Championship (Noack Cup), and the women's doubles event was known as the Northern California Championship (Klune & Floberg Trophy). In 1902 a singles event called the Northern California Championship for Tennis Singles was added to the schedule.

The tournament however was not held continuously and remained a sanctioned Pacific States LTA sanctioned event. In 1953 the Northern California Lawn Tennis Association was established as a separate sectional body within the United States Lawn Tennis Association.
