  Recent high-resolution observations with the Hubble Space Telescope (HST)
reveal that young star clusters of extraordinary luminosity and compactness
("super star clusters") are commonly found in starburst systems. Cluster
formation appears to be a dominant mode of star formation in starbursts. The
principal properties of the young clusters are summarized. A new ultraviolet
HST imaging survey of the central regions of nearby galaxies indicates that
young clusters form in a wide range of environments. Circumnuclear star-forming
rings, in particular, are richly populated with clusters, and several examples
from recent imaging studies are discussed. There has been much speculation that
super star clusters represent present-day analogs of young globular clusters. I
will present evidence suggesting that at least some super star clusters indeed
have masses and mass densities comparable to those of evolved globular clusters
in the Milky Way.
