GRETINA is a next-generation gamma-ray detector array under construction at Lawrence Berkeley National Laboratory. It makes use of the new technology of gamma-ray tracking to greatly improve both efficiency and resolution for in-beam spectroscopy. The principles of gamma-ray tracking will be described, together with the complex digital signal processing that makes it possible, the status of GRETINA, and plans for its utilization. Finally, a possible future tracking array, covering the full 4pi steradians and called GRETA, will be described.
