Nine by Nine was a nine-member Thai boy group formed in 2018. The members were brought together in a special one-year project created in collaboration of 4Nologue with Nadao Bangkok. From 2018 to 2019, the group has released one mini-album and five songs, embarked on a three concert series, and appeared as cast members for Thai TV series In Family We Trust and Great Men Academy. The group disbanded in March 2019 when the duration of the special project has formally ended.
