The chapter presents a comprehensive understanding on the recent advancements in creep of high-entropy alloys (HEAs). The creep response of the HEAs is segregated on the basis of crystal structure, number of phase constituents (single or multiphase), and their microstructures. The underlying deformation mechanisms on the basis of several key factors such as temperature, stress range, stress exponent, and activation energy are discussed. Various creep mechanisms, namely grain boundary diffusion- and lattice diffusion-mediated creep, dislocation glide- and climb/cross slip-controlled creep, and their complex interplay in various HEAs are also thoroughly addressed. After a thorough assessment, future perspective on designing HEAs with improved creep resistance is also provided.
