KSPX-TV (channel 29) is a television station in Sacramento, California, United States, airing programming from the Ion Television network. It is owned and operated by the Ion Media subsidiary of the E. W.

The station first signed on the air on August 27, 1990 as KCMY; it originally operated as the area's Home Shopping Club affiliate before joining the InfoMall TV network in the mid-1990s. In 1995, then-CBS affiliate KXTV agreed to  provide some programming to KCMY in order to give it more of a competitive edge in the Sacramento market. KCMY began airing the tabloid show "Geraldo" at 10 p.m. as well as the KXTV-produced health magazine show "Pulse". Paxson Communications (now Ion Media) purchased the station in 1998, changing its call sign to KSPX. The station became a charter owned-and-operated station of its new Pax TV network (later i: Independent Television and now Ion) on August 31, 1998. Technical information. Subchannels.
