Kasra Farahani (born March 1, 1978) is an Iranian-born American production designer, director, and writer. Born in Iran and raised in Los Angeles after his family fled the Islamic Revolution, he developed an early interest in drawing, architecture, and industrial design, later studying at ArtCenter College of Design from 1997 to 2000. He began his career in the art department as an illustrator and concept artist.

Farahani transitioned to production design on long-form and independent projects, serving as production designer on the digital miniseries Halo 4: Forward Unto Dawn (2012), for which he won a Streamy Award for Best Production Design.

His most prominent work has been serving as production designer on Marvel Studios' Loki, shaping the show's retro-futurist, time-bending aesthetic. He earned a Primetime Emmy Award nomination for Outstanding Production Design for a Narrative Period or Fantasy Program for the episode "Glorious Purpose," and won the Art Directors Guild Award for Excellence in Production Design for One Hour or Fantasy Single-Camera Television Series for the same episode. He later received an additional Art Directors Guild nomination for season 2's "Ouroboros", as well as recognition from the Set Decorators Society of America. Beyond designing the aesthetic of the series, he wrote and directed an episode of the second season, and also served as a staff writer for the season.

Alongside his design career, Farahani pursued writing and directing. He made his narrative directing debut with the short film Noon (2013), which was optioned for feature development, and later directed the features The Good Neighbor (2016) and Tilt (2017), also serving as writer and producer on selected projects.
