Abstract	The prospects for detecting gravitational waves from neutron star rotational glitches in the Advanced Detector Era and beyond are reviewed. Three possible signals are identified: (i) a burst during the glitch itself, generated by stellar oscillations or superfluid vortex reorganization; (ii) a long, quasimonochromatic transient which lasts days to weeks and is generated by nonaxisymmetric superfluid flows during the post-glitch recovery phase; and (iii) persistent inter-glitch continuous wave emission associated with vortex avalanche dynamics. Data analysis strategies are reviewed for the three classes of signal. It is shown that a detection, combined with radio timing data, can be inverted to place interesting constraints on the compressibility, viscosity, and state of superfluidity of bulk nuclear matter in the many-body, MeV-energy regime, under physical conditions that cannot be replicated on Earth.
