'''Lacepede Bay''' ({{IPAc-en|local|ˈ|l|æ|s|ə|ˌ|p|iː|d}} {{respell|LASS|ə|peed}}, {{langx|fr|Baie Lacépède}}) is a [[bay]] in the Australian state of [[South Australia]] located on the state's south-east coast about {{convert|140|km|abbr=off}} northwest of [[Mount Gambier, South Australia|Mount Gambier]] and about {{convert|240|km|abbr=off}} southeast of [[Adelaide]]. It was named in 1802 by the [[Baudin expedition to Australia|Baudin expedition of 1800-03]] after [[Bernard Germain de Lacépède]], the French naturalist. It is one of four ‘[[historic bay]]s’ located on the South Australian coast.

==Description== Lacepede Bay was named in 1802 by [[François Péron|Peron]] and [[Louis de Freycinet|Freycinet]] of the Baudin expedition of 1800-03 after Bernard Germain de Lacépède, the French naturalist.{{citation needed|date=July 2014}} Lacepede Bay lies between a locality known as Granite Rocks at its northern extremity and [[Cape Jaffa]] at its southern extremity on the south-east coast of South Australia. The bay is described as:<ref name=Pub175>{{cite enroute|175|2017|228}}</ref> <blockquote>The sandy shore is backed by sandhills, gradually decreasing in height, for a distance of {{convert|7|nmi|km|0}} S[outh] of Granite Rocks. [[Kingston SE, South Australia|Kingston]] is situated on the S[outh] side of the entrance to Maria Creek, at the head of the bay. Between Kingston and Cape Jaffa, the land is low and swampy, with a wooded bank behind the sandy beach; there is a prominent white sand patch on the bank above the beach, {{convert|9|nmi|km|0}} SW of Kingston. </blockquote> Lacepede Bay is one of four bays on the South Australian coast considered by the [[Australian government]] to be a ‘historic bay’ under the ''Seas and Submerged Lands Act 1973'' and was proclaimed as such in 1987 and again in 2006 and 2016 with the result that the mouth of the bay is on the [[Baseline (sea)|territorial seas baseline]] and the waters within the bay are [[internal waters]] as per the definition used in [[United Nations Convention on the Law of the Sea]].<ref>{{cite web|title=Article 8 Internal waters, Part II, UN Convention on the Law of the Sea|url=https://www.un.org/Depts/los/convention_agreements/texts/unclos/part2.htm|publisher=United Nations Convention on the Law of the Sea|access-date=29 July 2014}}</ref><ref>{{cite web|title=EXPLANATORY STATEMENT Issued by the authority of the Attorney-General, Seas and Submerged Lands Act 1973, Seas and Submerged Lands (Historic Bays) Proclamation 2006|url=http://www.comlaw.gov.au/Details/F2006L00526/Explanatory%20Statement/Text|publisher=Commonwealth of Australia|access-date=29 July 2014}}</ref><ref>{{cite web|title=Seas and Submerged Lands (Historic Bays) Proclamation 2016 |url=https://www.legislation.gov.au/Details/F2016L00301 |publisher=Commonwealth of Australia|date=10 March 2016 |access-date=11 October 2016}}</ref>
