KVEO-TV (channel 23) is a television station licensed to Brownsville, Texas, United States, serving the Lower Rio Grande Valley as an affiliate of NBC and CBS. It is owned by Nexstar Media Group alongside Harlingen-licensed KGBT-TV (channel 4), which airs Antenna TV and MyNetworkTV. The two stations share studios on West Expressway (I-2/US 83) in Harlingen; KVEO-TV's transmitter is located in Santa Maria, Texas.

KVEO-TV was the third major commercial station to start in the Rio Grande Valley, beginning broadcasting on December 19, 1981. It immediately became the full-time NBC affiliate in the market. Its original ownership was rocked by financial problems and connections to a failed bank; it emerged from bankruptcy in 1984. Two attempts at local newscasts (1981–1982 and 1985–1986) lasted less than two years each. The station was sold to what became Communications Corporation of America (ComCorp) in 1990. ComCorp began airing local news programming on the station again in 2007, though beginning in 2010 this was produced out-of-market at another station in the company.

Nexstar acquired KVEO-TV in 2013. In 2020, it acquired from Sinclair Broadcast Group all of the non-license assets of KGBT-TV, which had been the CBS affiliate, and its facilities. KGBT-TV's programming became the CBS subchannel of KVEO-TV, and news programming was realigned on both channels.

The first construction permit for channel 23 at Brownsville was awarded to Pan American Broadcasting Corporation in 1974; officials intended to build the station as the missing network affiliate for the market, then ABC. The station got as far as receiving call letters, but no building activity occurred. In 1978, the FCC review board granted an extension of time, noting that Pan American had attempted to merge with another proposed UHF station at McAllen; that merger fell through, and the group was allowed to try and transfer the permit.

The Pan American permit never materialized, and the channel was empty when Tierra del Sol Broadcasting Corporation applied on October 21, 1979, for channel 23. It immediately sought NBC affiliation; at the time, the city had a dual NBC–CBS affiliate, KGBT-TV, that had to try and provide the best programs from both networks and manage conflicts in such areas as sports.

During construction, Tierra del Sol Broadcasting sought to change electricity providers for its studio facility. The KVEO-TV studio building, the former The Godfather nightclub in Brownsville, was originally to be served by the city-owned Public Utility Board (PUB). However, it had a poor reputation for reliability, and brownouts were frequent on the system. The station desired to be served by Corpus Christi-based Central Power & Light (CP&L). It cited a 1975 Texas court decision that allowed it to become a CP&L customer because of its proximity to a CP&L line; when the PUB refused to disconnect its service to the building to permit the change in provider, KVEO did so itself with CP&L's permission, an action that the PUB then appealed to Texas utility regulators in addition to charging the station with criminal mischief. KGBT-TV ceased airing NBC programming on July 1, 1981, at which time KVEO ran newspaper advertising promising it would be on the air in less than 60 days with the NBC programs that would temporarily go unseen in the Valley. However, tower construction delays kept the station off the air.

KVEO began broadcasting on December 19, 1981. It struggled to find an audience, particularly for its Total 23 News programming, with viewers already tuned to KGBT-TV and KRGV-TV. The station's early evening newscasts were canceled in July 1982, followed by the late news that September. Additionally, the Mexican peso slumped beginning in February 1982, two months after the station signed on. That provoked a sharp decline in business activity on the American side of the Rio Grande and created further issues for a station that was already burdened with debt.

In order to raise cash for operating expenses, Peter Dean—one of the partners in Tierra del Sol and its chairman of the board—sold the station's uncollected advertising accounts to a company known as Central Texas Factors. Dean had helped to organize the company with Lawrence Ludka, his law partner; involved in the firm were several principals of the Ranchlander National Bank, a financial institution in the small town of Melvin. Tierra del Sol sued Dean and Ludka in October 1982 for splitting the revenues derived from this business without its knowledge or consent. In response, Dean moved to force KVEO into bankruptcy, claiming it owed him more than $600,000. Another owner of Tierra del Sol, Darrell Davis—who had anchored the station's newscasts prior to their cancellation—called Dean's actions malicious. Davis told The Brownsville Herald, "Mr. Dean has done us and the Valley wrong, and he is in for the most interesting time of his life." Dean's issues were magnified when the Ranchlander National Bank failed on November 19, its de facto owner having been revealed to be a former felon convicted for bank embezzlement. The probe into bank fraud and related broadcasting activity broadened shortly before Christmas as investigators looked into Central Texas Factors. On December 21, 1982, Peter Dean was found dead on a ranch owned by his father-in-law in Comal County. The medical examiner determined that he had died from drinking cola laced with cyanide, though there was also a hose attached to the vehicle's exhaust, and traces of carbon monoxide were found in his body.
