The Agreed Measures for the Conservation of Antarctic Fauna and Flora is a set of environmental protection measures which were accepted at the third Antarctic Treaty Consultative Meeting in Brussels in 1964. The Agreed Measures were formally in force as part of the Antarctic Treaty System from 1982 to 2011, when they were withdrawn as the principles were now entirely superseded by later agreements such as the 1991 Protocol on Environmental Protection to the Antarctic Treaty. The Agreed Measures were adopted in order to further international collaboration within the administration of the Antarctic Treaty System and promote the protection of natural Antarctic ecological systems while enabling scientific study and exploration.

The Agreed Measures were the first attempts under the Treaty to prioritise wildlife conservation and environmental protection. This was needed due to increasing human interest in exploration, science, and fishing, which had put pressure on natural flora and fauna. They proved successful, and led the way for more stringent environmental protection in future.
