KCSO-LD (channel 33) is a low-power television station in Sacramento, California, United States, serving as the local outlet for the Spanish-language network Telemundo. Owned and operated by NBCUniversal's Telemundo Station Group, KCSO-LD maintains studios on Media Place in the Woodlake neighborhood of Sacramento, and its transmitter is located in Walnut Grove, California. The station is also sister to regional sports networks NBC Sports Bay Area and NBC Sports California.

Due to its low-power status, KCSO-LD simulcasts in high definition on Ion Television outlet KSPX-TV (channel 29) on a subchannel displayed as channel 33.2 and in widescreen standard definition on independent station KMAX-TV (channel 31) on subchannel 31.7. KCSO-LD also operates Class A translator station KMUM-CD in Sacramento and also relies on cable and satellite to reach the entire market.

KCSO formerly operated translator KMMW-LD in Stockton; this station ceased operations in March 2025 and its license was returned to the Federal Communications Commission (FCC).
