The Stellarator of Costa Rica 1 (or SCR-1) is a small modular stellarator for the magnetic confinement of plasma located at Cartago, Costa Rica. It is developed by the plasmaTEC group of the Plasma Laboratory for Fusion Energy and Applications at Costa Rica Institute of Technology.{{Cite journal|last1=Mora|first1=J.|last2=Vargas|first2=V.

SCR-1 is of a compact design and has the distinction of having the smallest aspect ratio of any operating stellarator device (>4.4). Its design is influenced by the small Spanish stellarator UST-1.{{Cite journal|last1=Barillas|first1=L.|last2=Vargas|first2=V.
