Measurements of the millimeter wave sky provide a wealth of cosmological and astrophysical information. These measurements constrain primordial gravitational waves and inflation, provide new constraints on the dark universe, map the distribution of matter through gravitational lensing and the Sunyaev–Zeldovich effects, and measure the time varying millimeter wave sky. Simons Observatory and CMB-S4 represent the next two generations of cosmic microwave background observatories. In this talk I will give an overview of the science these projects will enable, present the instrument designs, and discuss the status of these projects.
