Resum
Massive stars are strongly linked to the production of non-thermal 
emission. The strong winds produced by massive stars feed with matter 
the accretion process and can lead to the generation of jets, which are 
detected in radio and also emit high-energy photons. In addition, 
powerful collimated outflows from massive protostars interacting with 
the ISM can lead to the acceleration of particles and subsequent 
non-thermal emission from radio to high energies. Finally, shocks linked 
with the stellar wind in binary systems, either formed by two massive 
stars or by a massive star plus a young pulsar, can lead to the 
production of broadband non-thermal radiation. In this talk, I will 
briefly describe the sources and go through the most relevant mechanisms 
of non-thermal emission in which massive stars are involved.
