Carlisle S. Abbott (February 26, 1828 – March 31, 1919) was a Canada-born pioneer who migrated to the United States during the California Gold Rush.

Abbott was born on February 26, 1828, near Lake Memphremagog, Quebec, twelve miles north of the border separating Canada and Vermont.

His ancestry can be traced back to George Abbott, an English settler, who settled in Andover, Massachusetts, following the conclusion of the Revolutionary war.

After spending some time in the gold mines of Sacramento County, California, he returned to Beloit via Panama, arriving in New York on Christmas day in November 1851.

Their honeymoon involved a return trip to California, during which Abbott led a caravan consisting of sixty oxen, fifty cows and heifers, five wagons, ten horses, and took eighteen men and passengers.

Later, Abbott acquired 12,000 acres (4,900 ha) of the Rancho San Lorenzo at the valley's southern end, where he continued farming and sheep rearing.
