Line Manga is a digital manga and webtoons distribution platform launched in 2013 by Line Corporation and operated by Line Digital Frontier since 2018. The service initially offered only licensed manga.

One of the biggest features of the service was its integration with the Line messaging app, users could recommend and share manga titles with friends in the app, collect special stickers that were exclusive to titles bought on the service, and use Line's digital currency to buy titles. In 2017, Line Manga introduced the ability to read some manga chapters for free similar to the webtoon model it had used with its Naver Webtoon service.

Naver, Line's Korean owner, in 2018 decided it would close down its Japanese service of Naver Webtoon (known as XOY in Japan) and merge it with Line Manga, bringing with it not just its translated webtoons but also its domestic Japanese webtoons to the service.

Following the integration, Japanese-translated versions of webtoons from Webtoon began to be featured on the platform under the label Line Manga Webtoon, making Line Manga the Japanese counterpart to Webtoon.

Since its launch, it has grown to be the second most popular manga app in Japan behind Piccoma and has reached over 23 million downloads since its inception.
