The 2021 August 14 M_W 7.2 Nippes, Haiti earthquake occurred 75 km west of the epicenter of the 2010 Leogane earthquake (Haiti) on the transpressive Caribbean - North America (CA-NA) plate boundary. We present an updated fault map for Hispaniola and model coseismic and early postseismic fault slip using Interferometric Synthetic Aperture RADAR (InSAR) and pixel offsets. We find the earthquake ruptured multiple segments of the Enriquillo-Plantain Garden Fault Zone (EPGFZ). Slip occurred in two main sub-events separated by 60 km on either side of a restraining bend at Pic Macaya, with ~2.7 m of peak reverse-slip east of the bend. To the west, slip jumps the restraining bend and further ruptures with ~1.3 meters of left-lateral slip. Afterslip in the four days following the event occurred at shallow depth and adjacent to the coseismic rupture areas and reached the surface to the east of Pic Macaya.
