  High-mass stars are major players in the chemical and dynamical evolution of
galaxies. Open clusters and associations represent the natural laboratories to
study their evolution. In this review, I will present a personal selection of
current research topics that highlight the use of open clusters to constrain
different properties of high-mass stars, such as the possible existence of an
upper limit for the mass of a star, the evolutionary stage of blue supergiants
or the characterisation of supernova progenitors.
