非文档（non-paper，拉丁文aide-mémoire），是指在国际关系中，为了便于谈判和讨论而使用的非正式文本。“非文档”主要目的是便于将讨论过程中的内容落实在文本上，以便进一步协商。但为了防止“非文档”产生某种法律上的效力，“非文档”通常无编号、无落款、无日期、无标题，不会被检索和引用。

In international relations, an aide-mémoire is a proposed agreement or negotiating text circulated informally among delegations for discussion without committing the originating delegation's country to the contents. It has no identified source, title, or attribution and no standing in the relationship involved. Such a text is also referred to as a non-paper in many international organizations, including the General Agreement on Tariffs and Trade/World Trade Organization and sometimes within the European Union.
