Dust results in a variety of effects in many aspects of supernova observations. Firstly, the observations of some supernovae and supernova impostors show signatures of dust emission. These can originate from newly formed dust in the supernova ejecta, newly condensed dust in the shocked cool dense shell (CDS) of supernovae interacting with the circumstellar medium (CSM), or from pre-existing dust in the CSM. However, observationally it is often difficult to distinguish between the different scenarios. Secondly, many supernovae suffer from significant host galaxy line-of-sight extinction, in particular in high star formation rate environments, such as in luminous infrared galaxies. It is crucial to understand the missing fractions of core-collapse supernovae in these dusty environments to correct for the observed supernova rates from the local to the high-redshift Universe during the era of next-generation surveys like the LSST. I will summarize the basic characteristics of these dust effects and highlight a selection of related individual events particularly relevant to the theme of shocking supernovae.
