These lectures, presented at TASI 2018, provide a concise introduction to\ninflation, baryogenesis, and aspects of dark matter not covered by the other\nlectures. The emphasis for inflation is an intuitive understanding and\ntechniques for constraining inflationary models. For baryogenesis we focus on\ntwo examples, leptogenesis and electroweak baryogenesis, with attention to\nsinglet-assisted two-step phase transitions. Concerning dark matter, we review\ndifferent classes of models distinguished by their mechanisms for obtaining the\nobserved relic density, including thermal freeze-out, asymmetric dark matter,\nfreeze-in, SIMP dark matter, the misalignment mechanism for ultralight scalars\nand axions, and production of primordial black holes during inflation. Problem\nsets are provided.\n
