Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. The direct production of electroweak SUSY particles, such as sleptons, charginos, and neutralinos, is a particularly interesting area with connections to dark matter and the naturalness of the Higgs mass. We are exploring this experimentally challenging frontier with the large integrated luminosity of Run 2 and new experimental techniques. This talk will present results from searches for electroweak SUSY partners using data collected with the ATLAS experiment in Run 2 at the LHC. We use several different signatures to search for direct production of electroweak particles, and interpret the results as constraints on a variety of SUSY models.
