The quest to harness magnonic spin waves, aided by insights from topological matter, has
led to the emergence of the new field of topological magnonics. Among the systems that have
been predicted to support topologically protected magnonic edge states are spatially periodic
noncollinear textures. A noteworthy example are skyrmion crystals, which have garnered
much interest lately due to their topological transport properties and the potential to use
skyrmions as information carriers in future high-density, low-power storage and logic
devices. In this talk I will discuss our latest findings on topologically protected magnonic
edge states in antiferromagnetic as well as ferromagnetic skyrmion crystals.
