Adachi and Shimamura (安達としまむら, Adachi to Shimamura) is a Japanese yuri light novel series written by Hitoma Iruma and illustrated by Non, which began serialization in October 2012 in ASCII Media Works' Dengeki Bunko Magazine and is published under the Dengeki Bunko imprint.

First-year high school students Sakura Adachi and Hougetsu Shimamura encounter each other by chance one day while skipping class, and become friends.

The original light novel series, written by Hitoma Iruma and illustrated by Non, was first serialized in ASCII Media Works' Dengeki Bunko Magazine in October 2012.

It was initially announced that the twelfth volume would be the final installment of the series,[17] but in April 2024, Iruma stated in a blog post that he planned to continue it further.

[69] Funimation acquired the series and streamed it on its website in North America and the British Isles, and on AnimeLab in Australia and New Zealand.

In early reviews, Ballard said that it is similar to Bloom Into You and called it "a heartwarming coming-of-age story" while noting the "growing friendship" between Adachi and Shimamura, as their relationship expands, and their bond strengthens.

"[82] A review of the first volume in Publishers Weekly called the series "oddly voyeuristic" and felt it was "inexplicably" being marketed to an adult audience.

The review further criticized the characters as "flimsy adult fantasies" with no complexity, and concluded by saying that it may have appeal with a teenaged audience but would not interest older readers.
