KECA-LD (channel 29) is a low-power television station in Eureka, California, United States, affiliated with The CW Plus and MyNetworkTV.

Sinclair also provides certain services to Fox affiliate KBVU (channel 28) under a local marketing agreement (LMA) with Cunningham Broadcasting; however, Sinclair effectively owns KBVU as the majority of Cunningham's stock is owned by the family of deceased group founder Julian Smith.

The four stations share studios on Sixth Street in downtown Eureka; KECA-LD's transmitter is located along Barry Road southeast of the city.

The CW and MyNetworkTV first appeared in Eureka respectively on KUVU-LP (channel 9) and KEMY-LP (channel 33), both analog-only stations and the latter a semi-satellite of KRVU-LP in Redding, as part of the Eureka Broadcast Group, which owned CBS affiliate KVIQ and several other stations with affiliations to Fox, UPN, The WB and others.

KUVU and KEMY were dissolved in 2014 and Bonten Media Group, who had purchased most of the Eureka Broadcast Group stations including KUVU and KEMY in 2012, launched KECA as a digital replacement for the two defunct stations in the Eureka market.
