Lachlan Turczan (b. 1993) is an American artist whose work investigates the optical and sonic properties of water. Drawing on natural phenomena to alter human perception, Turczan creates installations that merge light, sound, and fluid dynamics into immersive experiences.

He graduated from the Rhode Island School of Design in 2015 with a degree in Media Studies. During his time at RISD, he took courses in glass, neuroscience, and computer animation to inform his interests in optics, perception, and movement. Over the past decade, Turczan has presented his work internationally at museums, design fairs, music festivals, and experimental film screenings. Most recently, he premiered Lucida (I–VI), a new series of monumental light sculptures developed in collaboration with Google for Milan Design Week 2025.
