The 2020 Mi'kmaq lobster dispute is an ongoing lobster fishing dispute between Sipekne'katik First Nation members of the Mi'kmaq and non-Indigenous lobster fishers mainly in Digby County and Yarmouth County, Nova Scotia. The dispute relates to interpretations of R v Marshall, a 1999 Supreme Court of Canada ruling upholding the Halifax Treaties, empowering Indigenous Canadians the right to fish. Non-Indigenous fishers negatively reacted to off-season fishing activities of a self-regulated Indigenous lobster fishery, mainly citing concerns of potential overfishing.
