Rincon de los Esteros, also known as Innovation Triangle,[1][2] the Golden Triangle,[3][4] the Innovation District,[5] or simply as Rincon,[6] is a vast district of San Jose, California, making up a significant portion of North San Jose.

[7][8][9] The district has one of the largest concentrations of high tech company headquarters and campuses in Silicon Valley.

[10][11] The Rincon de los Esteros district of San Jose has its origins in the old Rancho Rincón de los Esteros, a Mexican-era rancho granted to local Californio ranchero Ignacio Alviso by Governor Juan Bautista Alvarado in 1838.

In 1974, the government of San Jose instituted the Rincon de los Esteros Redevelopment Plan, to develop the Rincon de los Esteros district into a major tech hub for Silicon Valley.

[16][17][18] Rincon is also known as Innovation Triangle and is one of the most important high tech hubs in Silicon Valley.
