LUX-ZEPLIN (LZ) is a xenon-based direct detection dark matter experiment, currently under construction about one mile below ground at the Sanford Underground Research Facility in the USA. The experiment's 5.6 tonnes of fiducial volume will be a 22-fold increase over its predecessor, LUX. This will allow the experiment to be sensitive to 40 GeV WIMPs with spin-independent cross-sections as low as 1.6x10^{-48} cm^2 at 90% C.L. following an exposure of 1000 live days, which will begin in 2020. LZ is designed around a two-phase xenon time projection chamber, contained in an ultra-low background titanium cryostat, and surrounded by several auxiliary veto systems including an outer liquid xenon layer and a gadolinium-doped liquid scintillator detector. This presentation gives an overview of the experiment, its current status and timeline, and the predicted sensitivity and backgrounds.
