"Like Ooh-Ahh" is a song recorded by South Korean girl group Twice, the lead single of their debut extended play (EP) The Story Begins. It was released on October 20, 2015 by JYP Entertainment and distributed by KT Music. It is written and composed by Black Eyed Pilseung and Sam Lewis.

"Like Ooh-Ahh" is described as a 'color pop' dance track with elements of hip-hop, rock, and R&B. The composition team included Black Eyed Pilseung and lyricist Sam Lewis, known for producing successful releases such as Miss A's "Only You."

On October 20, 2015, the song's music video was released online. It was directed by production team Naive (Kim Young-jo and Yoo Seung-woo).

The video begins with Twice in a run-down hospital filled with zombies. However, the members barely notice them and continue dancing and singing through the halls, the roof, a bus, and leading to a space eventually with the zombies themselves. It ends as one of the zombies hearing his own heartbeat and slowly turning back into a human.

Within five months after its release, the video hit 50 million views on YouTube and replaced 2NE1's "Fire" as the most-viewed debut music video for any K-pop group. It went on to hit 100 million views on November 11, 2016, making Twice the fourth K-pop girl group to reach this milestone, as well as the first debut music video to do so.

"Like Ooh-Ahh" debuted at number 22 on Gaon Digital Chart until it reached its peak position at number 10, three months after its release. It also peaked at number 6, 27 and 59 on Billboard charts' World Digital Songs, Billboard Japan Hot 100 and Philippine Hot 100, respectively.
