• The elastic performance of kirigami metallic glasses (MGs) plays a key role for their applications as potential mechanical metamaterials, however, the mechanisms on how to achieve programmable large elasticity in these kirigami MGs are still unknown. In this work, kirigami MGs, with programmable stretchability reaching 317%, were fabricated, demonstrating super elasticity larger than 277%. The high stretchability and super-elasticity are mainly attributed to the elastic out-of-plane bending of the kirigami elements rather than rigid deformation. The super elastic kirigami MGs can be developed for use as high stretchable mechanical/functional metamaterials/devices, such as wearable sensors and stretchable electronics. [Display omitted] •Programmable stretchability reaching 317% and a super elasticity larger than 277% are achieved in kirigami metallic glasses (MGs).•The design of circle-shaped node-cuts significantly affects the elastic performance of kirigami MGs.•The super elasticity of kirigami MGs is attributed to the elastic bending of kirigami elements.
