DEAP-3600 is a novel liquid argon (LAr) based direct dark matter search located 2 km underground at SNOLAB. The detector consists of a 3279 kg LAr target contained in a radiopure acrylic vessel viewed by 255 high quantum efficiency photomultiplier tubes (PMTs). Shielding from radiogenic neutrons is provided by polyethylene and acrylic. Cosmogenic backgrounds are suppressed by immersing the detector in 373 tonnes of ultrapure water viewed by 48 outward facing PMTs. The atmospheric LAr target contributes a background of 39Ar which is heavily suppressed by the best demonstrated pulse-shape discrimination in a LAr detector. This talk will highlight the recent analysis and results from 231 live-days of data in DEAP-3600 which is the most sensitive WIMP search above a mass of 30 GeV/c2 using argon.
