LeeMujin Service () is a South Korean talk show and live music web television program hosted by South Korean singer-songwriter Lee Mu-jin. First airing on 22 February 2022, the program airs every Tuesday at 6 pm KST on the YouTube channel KBS Kpop, and re-runs air on KBS2 every Tuesday at 11 pm KST.
The program features live music performances from individual idol group members and solo acts, without an audience. The name of the show is a pun on the phrase "limousine service"; the Korean pronunciation of "limousine" sounds identical to the American pronunciation of the host's name "Lee Mu-jin."
The format involves a guest opening the show with the most recent song released by the guest's group (or their own song if the guest is a solo artist). The show then proceeds with the guest singing two songs (called "live services") and is followed by a duet song with Lee. The set list for each show is planned in advance. The only instrumental accompaniment in the show is from a keyboardist. In addition to the two "live services" and the duet, Lee asks the guest about their music career and also asks the guest to sing fragments of other songs (like their audition song, a song from a different genre, a song from a senior singer they admire, and so on).
This show marks Lee Mu-jin's debut as an MC.

In an episode broadcast on 25 June 2022, Lee Mu-jin appeared as a contestant in ', Hwang Chi-yeul praised Lee saying: "He is good at talking and sings well. After one or two broadcasts, when I watch TV at home, I think, I wish I had done that."
On March 6, 2025, media reported that Lee Mu-jin was absent for the taping of episode 157 (aired on March 18, 2025) with Nmixx's Kyujin as the guest. Lee Mu-jin is represented by BPM Entertainment, the parent company of One Hundred, which represents EXO's Xiumin. Recently, One Hundred accused KBS of unofficially blocking Xiumin from appearing on shows that feature SM Entertainment artists, following the ChenBaekXi contract dispute. They further claimed that KBS's entertainment director has ignored their requests for two weeks, failing to confirm Xiumin's participation in comeback broadcasts. As a result, Mu-jin was ordered not to attend the taping of his own show, leaving Kyujin to introduce herself and sing alone during the episode. He apologized to the audience on the next episode and in episode 186 he apologized to Kyujin after she returned to the show.
