KLMG-TV, virtual channel 51 (UHF digital channel 31), is a CBS-affiliated television station serving Tyler, Texas, United States that is licensed to Longview. Owned by White Knight Broadcasting, it is a sister station to Tyler-licensed low-power UPN affiliate KTPN-LD (channel 48); Nexstar Media Group, which owns Jacksonville-licensed NBC affiliate KETK-TV (channel 56), operates KLMG-TV and KTPN-LD under a shared services agreement. The three stations share studios on Richmond Road (near Texas Loop 323) in Tyler; KLMG-TV's transmitter is located near FM 125 in rural northwestern Rusk County (northwest of New London).

Although KLMG-TV operates a full-power signal, the broadcasting radius does not reach much of the southern part of the market. Therefore, it is relayed on low-power translator station KFXL-LD (UHF channel 29, also mapped to virtual channel 51 via PSIP) in Lufkin. This station's transmitter is located on SH 103 near Loop 287 northwest of Lufkin.
