Between 1841 and 1844, during the period when Alta California was a territory of independent Mexico, four Mexican land grants were made in what became Merced County: Rancho Orestimba y Las Garzas, Rancho Panoche de San Juan y Los Carrisolitos, Rancho San Luis Gonzaga, and Rancho Sanjon de Santa Rita
Merced County was formed in 1855 from parts of Mariposa County. Parts of its territory were given to Fresno County in 1856.
