My Neighbor Seki (となりの関くん, Tonari no Seki-kun) is a Japanese manga series written and illustrated by Takuma Morishige.

The series follows a girl named Rumi Yokoi who is constantly distracted by her neighboring classmate, Toshinari Seki, as he indulges in elaborate hobbies and somehow never gets caught in the process.

A spin-off series titled My Neighbor Seki-kun Junior launched in the July 4, 2020 issue of Monthly Comic Flapper.

The fifth manga volume was released simultaneously on January 4, 2014 with a limited edition, bundled with an original animation DVD containing two additional episodes.

[46] Karen Mead of Japanator liked that the anime put the detail into Seki's projects rather than the characters, and that while the show could have worked as a three- to four-minute short, that it gets stretched to eight minutes with opening and ending themes gives it a chance to build atmosphere and tension.
