We report the results of de Haas­van Alphen measurements in high magnetic fields on the anisotropic
compound LaSb2 . Our measurements reveal three extremal orbits of the Fermi surface. One is very small and
ellipsoidal, while the remaining two are larger and have a nearly cylindrical shape indicating a quasi-two-
dimensional Fermi surface. We compare these measurements with the results of energy band calculations and
find reasonable agreement with the measured Fermi surface areas, though the calculations show other multi-
connected regions of the Fermi surface not observed in the de Haas­van Alphen spectra. The implications of
