NetWare核心协定（英语：NetWare Core Protocol，缩写为NCP），一种网络协定，由Novell公司开发。它在Novell NetWare操作系统上开发出来，但是在部份Unix系统、Linux、Windows NT等也支持这个协定。

它的底层是 TCP/IP与IPX/SPX（这个协定已经过时，但在Netware上仍然提供支持），能够提供文件、打印机、目录等网络功能。

The NetWare Core Protocol (NCP) is a network protocol used in some products from Novell, Inc. It is usually associated with the client-server operating system Novell NetWare which supported primarily MS-DOS client stations, but more recently a support of other platforms such as Microsoft Windows, Mac OS, Linux, Windows NT and various flavors of Unix was added.
