"Doki Doki Morning" (ド・キ・ド・キ☆モーニング, Doki Doki Mōningu^?) (stylized as "Doki Doki ☆ Morning" and formerly "Do・Ki・Do・Ki ☆ Morning") is a song by the Japanese band Babymetal. The song was released in Japan as an independent DVD single on October 24, 2011, serving as the first single off the debut album Babymetal.

The song's first appearance was in the Sakura Gakuin album Sakura Gakuin 2010 Nendo: Message, released on April 27, 2011, as part of the Juonbu ("heavy music") sub-unit.

It was later released as a standard digital download and in a limited edition DVD single, which was first made available on October 22 and 23, 2011 for pre-sale at the Sakura Gakuin Festival ☆ 2011 held at Mt. Rainier Hall "Shibuya Pleasure Pleasure", and later sold in limited quantities on ASmart, Amazon, Tower Records Online, and Tower Records Shinjuku starting October 24. The limited edition included a DVD with the "Doki Doki ☆ Morning" music video and a cut of the original video, exclusively featuring choreography for live performances of the song, and a towel embossed with either the logo of the band or the label Juonbu Records.

The song has a "modern heaviness" sound in its music, with dark, atmospheric instrumentals that reverse into a catchier and brighter melody with lyrics such as "Ring ring ring! Good morning, wake up".

The song managed to peak at number 80 on the Billboard Japan Top Independent Albums and Singles chart.

Directed by Shimon Tanaka, the music video was released in an abridged form to the Toy's Factory YouTube channel on October 12, 2011, with the full version posted on the official Babymetal channel over a year later, on November 8, 2012.

Metal Injection ranked the music video at number nine on the list of "The Top 15 Metal Viral Videos of the Year" on December 8, 2011.

The song premiered at the Sakura Gakuin concert Sakura Gakuin Festival ☆ 2010 at the Yokohama Red Brick Warehouse No. 1 on November 28, 2010. Regarding the group's first performance of the song, Su-metal explained, "What I remember clearly was during the interlude […] we all pretend to fall to the ground...I was afraid that people would just laugh at us and it would be embarrassing, but their reaction made me feel happy and at that time I thought this is who Su-metal is, this is what Babymetal is."
