Music Station (ミュージックステーション, Myūjikku Sutēshon), stylised in all caps, is a Japanese music television program. Broadcasting live weekly on TV Asahi since October 24, 1986, it currently airs from 9PM-10PM on Fridays. The program is also colloquially known as M St. (Mステ, Emu Sute), MS (エムエス, Emu Esu), and M Station (Mステーション, Emu Sutēshon). The program has been aired internationally on Animax's networks in Southeast Asia, Hong Kong, Taiwan, and other regions from March 2007. It was also seen in the United States and Canada through the NHK-owned TV Japan until the network's closure at the end of March 2024 and was replaced by the Jme Japanese streaming platform, in Hong Kong via TVB J2 before it was renamed to TVB Plus in April 2024, in Singapore through Hello Japan! before the channel went off the air in July of 2015 and in the People's Republic of China through CCTV-15.

Music Station is a weekly one-hour music program similar to the American TRL or the British Top of the Pops. It is home to various performances as well as single rankings and other corners. Many Japanese musical acts make their debut on Music Station, but the show has also hosted many artists from around the world. As of October 2021, over 8,300 songs had been performed on the show.

From October 24, 1986, to March 31, 2000, Music Station was broadcast live on Fridays from 20:00–20:54 JST. It briefly switched to 19:54–20:48 JST from April 14 to September 15, 2000. The show returned to its previous schedule on October 6, 2000, and stayed there until September 13, 2019. After TV Asahi restructured its prime time slot, Music Station has been broadcast from 21:00–21:54 JST since October 18, 2019. This change was done to capture the young audience, whom, according to Tamori, are no longer home at 20:00.

On February 12, 2010, the show celebrated its 1000th episode with a special episode. In celebration of its 25th anniversary, Music Station launched its official YouTube channel and an internet show, Young Guns on the Web (based on its Young Guns segment).

Music Station has been hosted by famed Japanese TV-comedian Tamori since April 3, 1987. To date he has appeared in nearly every episode, marking over 1,360 appearances as the host. In 2021, he was certified as holding the Guinness World Record for "Longest running live TV music show hosted by the same presenter". The show is co-hosted by TV Asahi announcer Sarasa Suzuki [ja] (since October 7, 2022). The two provide banter for the show in between performances.

Sayaka Shimohira [ja] was the co-host from 1996 to 2000. Emi Takeuchi [ja], TV Asahi broadcaster, was the co-host from 2000 to 2004. Mariko Dō [ja] was the previous co-host from 2004 to 2008. Dō first appeared on the show on April 9, 2004. This episode was a 3-hour special titled: New Start Best 100. Dō joining the program was a surprise to the media, as she was new to the industry and had only been hired by TV Asahi nine days before becoming the co-host of a prime time program. After 4½ years, she graduated from the program on September 12, 2008, with Autumn Special Part 1. Yoshie Takeuchi served the co-host role from October 3, 2008, to September 27, 2013. Ayaka Hironaka was the co-host from October 18, 2013, to September 7, 2018. Marina Namiki was the co-host from October 19, 2018, to September 23, 2022.

Music Station is home to various weekly segments, the most common being the weekly singles ranking and the monthly album ranking.

The Music Station Ranking segment began in November 2017. It is a renewal of the "Music Topics" segment.
