Lunaria: Virtualized Moonchild is a Japanese science fiction visual novel developed by Key, a brand of Visual Arts. It was released on December 24, 2021 for Windows and is Key's 17th game overall. It was ported to iOS and Android devices, and also the Nintendo Switch. The story follows high school student Tabito Kamishiro, known as T-bit when playing the virtual reality racing game Skyout, which earns him an income in the form of prize money. One day, he wanders onto an unknown server on the Moon and meets the AI avatar Lunar-Q, who earnestly wants to see the Earth herself.

Lunaria is the fifth of Key's "kinetic novels"—beginning with Planetarian: The Reverie of a Little Planet (2004)—since its story offers no choices or alternate endings. Instead, the player proceeds through the story solely by reading. The story was written by light novel author Takeshi Matsuyama, and character design was shared between Key's in-house artist Fumuyun and Sora Saeki. The game's soundtrack was composed by Shinji Orito, Donmaru, Ryō Mizutsuki, Shōji Morifuji, Hisashi Tenkyū, Shōyu and Shinpei Nasuno.
