高端主机控制器接口（英文：Advanced Host Controller Interface，缩写：AHCI），是一种由英特尔制定的技术标准，它允许软件与SATA保存设备沟通的硬件机制，可让SATA保存设备启用高端SATA功能，例如原生指令队列及热插拔。AHCI详细定义一个内存架构规范给予硬件制造商，规范如何在系统内存与SATA保存设备间传输数据，目前（2014年3月）最新AHCI规范为1.3.1版。

许多SATA设备控制器可个别启用AHCI功能或与RAID功能合并使用，英特尔就建议如果在其支持AHCI芯片组上使用RAID功能，采取AHCI模式组建RAID可以获得最大弹性，因为AHCI可在完成安装的操作系统中切换RAID组建模式。

The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host bus adapters in a non-implementation-specific manner.

The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them.
