  A selection of new jet substructure measurements are reported from the ALICE
experiment at the CERN LHC in both proton-proton and heavy-ion collisions.
These include the first fully corrected inclusive measurements of the groomed
jet momentum fraction and the groomed jet radius, as well as the
$N$-subjettiness distribution and the fragmentation distribution of reclustered
subjets. We also report on the measurement of several groomed substructure
observables of heavy-flavor jets in pp collisions, fragmentation functions and
the new measurements of the radial distributions of D$^0$ mesons or
$\Lambda^+_c$ baryons in jets. The measurements are compared to theoretical
calculations and provide new constraints on the physics underlying parton
fragmentation and jet quenching.
