{{Legislation of the European Union}}The term '''''acquis communautaire''''' ({{IPA2|aˈki}}), or ''EU acquis'', is used in [[European Union law]] to refer to the total body of EU law accumulated thus far.

==Chapters of the Acquis==
During the process of the [[enlargement of the European Union]], the acquis
was divided into 31 chapters for the purpose of negotiation between the EU and the candidate member states for the fifth enlargement (the ten that joined in 2004 plus [[Romania]] and [[Bulgaria]] that joined in 2007). These chapters were:

{|
|-
|
#[[Free movement of goods]]
#[[Free movement of persons]]
#[[Freedom to provide services]]
#[[Free movement of capital]]
#Company law
#[[Competition policy]]
#Agriculture
#[[Fishery|Fisheries]]
#Transport policy
#[[Taxation

#[[Economic and Monetary Union of the European Union|Economic and Monetary Union]]
#Statistics
#Social policy and employment
#Energy
#[[Industrial policy]]
#Small and medium-sized enterprises

<li>Telecommunication and information technologies
<li>Culture and audio-visual policy
<li>[[Regional

<li>Environment
<li>Consumers and health protection
<li>Cooperation in the field of [[Justice and Home Affairs]]
<li>[[Customs union]]
<li>External relations
<li>[[Common Foreign and Security Policy]] (CFSP)
<li>Financial control
<li>Financial and budgetary provisions
<li>Institutions
<li>Others
</ol>

|}

For the negotiations with [[Croatia]] and [[Turkey]], the acquis was split up into 35 chapters instead, with the purpose of better balancing between the chapters: dividing the most difficult ones into separate chapters for easier negotiation, uniting some easier chapters, moving some policies between chapters, as well as renaming a few of them in the process:

Such negotiations usually involved agreeing transitional periods before new member states needed to implement the laws of the European Union fully and before they and their citizens acquired full rights under the ''acquis''.

==Other uses==
The term is also used to describe laws adopted under the [[Schengen treaty]], prior to its integration into the European Union legal order by the [[Treaty of Amsterdam]], in which case one speaks of the ''Schengen acquis''.

The term
''acquis'' has been borrowed by the [[World Trade Organization]] Appellate Body, in the case ''Japan - Taxes on Alcoholic Beverages'', to refer to the accumulation of [[GATT]] and WTO law ("''acquis gattien''"), though this usage is not well established.

It has been used to describe the achievements of the [[Council of Europe]] (a body unconnected with the European Union):
:The Council of Europe’s acquis in standard setting activities in the fields of [[democracy]], the [[rule of law]] and fundamental [[human rights]] and freedoms should be considered as milestones towards the great European political project, and the [[European Court of Human Rights]] should be recognised as the pre-eminent judicial pillar of any future architecture.
''(Section 12, Parliamentary Assembly of the Council of Europe Resolution 1290
)''

It has also been applied to the body of "principles, norms and commitments" of the [[Organization for Security and Co-operation in Europe]] (OSCE):

:Another question under debate has been how the Partners and others could implement the OSCE acquis, in other words its principles, norms and commitments on a voluntary basis.

''Intervention by Ambassador Aleksi Härkönen, Permanent Representative of Finland to the OSCE, Annual Security Review Conference'' [http://www.osce.org/documents/sg/2004/06/3241_en.pdf
]

The [[OECD]] introduced the concept of the OECD Acquis in its "[http://www.oecd.org/dataoecd/63/6/32036418.pdf Strategy for enlargement and outreach]", May 2004.
