OneDrive，全名Microsoft OneDrive，前称Windows Live SkyDrive，是微软所推出的网络硬盘及云端服务。用户可以上传他们的文件到网络服务器上，并且透过网络浏览器来浏览那些文件。更可直接编辑和观看Microsoft Office文档。同时推出同步上载软件，可于电脑直接访问和同步文件。另外，OneDrive并允许用户透过Microsoft Account来限制不同的用户访问文件，允许用户决定是否将文件与公众分享，或是限于联系清单上的人才能访问；而对所有人公开的文件则不需要Microsoft Account即可访问。

OneDrive (previously SkyDrive, Windows Live SkyDrive, and Windows Live Folders) is a file hosting service that allows users to sync files and later access them from a web browser or mobile device. Users can share files publicly or with their contacts; publicly shared files do not require a Microsoft account to access them. OneDrive is included in the suite of online services formerly known as Windows Live.
