Neon Heart (Portuguese: Coração de Neon, lit. '"Heart of Neon"') is a 2022 Brazilian drama film written and directed by Lucas Estevan Soares, and produced by Rhaissa Gonçalves. It stars Lucas Soares himself, Ana de Ferro and Wawa Black. In Neon Heart, Fernando (Soares) works with his father delivering romantic messages given as gifts to people all over town on board a telegram service car called Neon Heart.

Neon Heart is the first Brazilian film produced with Dolby Atmos 9.1 technology, which puts the viewer in a "bubble" in which the sound can be emitted from any position, depending on what occurs in the film, allowing the listener to perceive the difference between sounds received from different directions.

The film premiered at the 2022 WorldFest-Houston International Film Festival and was later released theatrically in Brazil on 9 March 2023. It received critical praise in and outside Brazil, and was awarded throughout 2022 at the Moscow, WorldFest Houston and FestCine Pedra Azul international film festivals.

At the 75th Marché du Film, an event held annually in conjunction with the Cannes Film Festival, Neon Heart was cited as "great example of the new Brazilian popular cinema".
