Yuri Landman (Zwolle, 1973) is a Dutch designer of musical instruments, musician and comics artist.

He builds experimental string instruments based on resonance and overtones — using third-bridge techniques, preparations and unusual tunings as a starting point. His instruments are part of the collection of the Musical Instrument Museum in Phoenix, Arizona.

Alongside his work as a builder, he gives workshops and masterclasses in instrument building, overtone theory and hacking culture at art academies, design schools and conservatories across Europe. In these workshops, participants build their own playable instrument — using his own designs or the synths of Error Instruments.

Since 2025 he performs in the duo Hakai 0+0 together with Paul Tas. As a comics artist he has published several graphic novels, including 1991 (2021).
