With the recent successful launch and commissioning of JWST, atmospheric characterization of exoplanets smaller than Neptune is finally firmly within reach. I will start by summarizing our understanding of low-mass (sub-Neptune and super-Earth) exoplanet atmospheres based on prior observations obtained with facilities like HST, Spitzer, and current ground-based telescopes. I will motivate several key outstanding questions that are expected to be addressed by JWST. I will then spend the remainder of my time presenting new JWST data of exoplanet atmospheres including some unpublished observations (no social media please!). I will conclude with a forward-looking view of what we can expect from the next few years of JWST exploration of low-mass exoplanet atmospheres.
