The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface.
It was announced by Apple in October 2008. As of 2013, all new Apple Macintosh computers had the port, as did the LED Cinema Display. However, in 2016 Apple began phasing out the port and replacing it with the new USB-C connector. The Mini DisplayPort is also fitted to some PC motherboards, and some PC notebooks from Asus, Microsoft, MSI, Lenovo, Toshiba, HP, Dell, and other manufacturers.
Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 (WQXGA) in its DisplayPort 1.1a implementation, and 4096×2160 (4K) in its DisplayPort 1.2 implementation. With an adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.
Apple offers a free license for the Mini DisplayPort but they reserve the right to cancel the license should the licensee "commence an action for patent infringement against Apple".

Compatibility
Apple replaced the DVI port from the MacBook, MacBook Air, MacBook Pro, iMac, Mac Mini, and the Mac Pro with the Mini DisplayPort. Its use as the video connector for the 24-inch Cinema Display may complicate compatibility:
- Mini DisplayPort's HDCP extension disables playback of certain DRM-encrypted content on any display not designed for it. This includes some content from the iTunes Store which has no such restrictions if played on a Mac without Mini DisplayPort.
- Apple's Dual-Link DVI or VGA adapters are relatively large and expensive compared to past adapters, and customers have reported problems with them, such as being unable to connect to an external display. Monitors connected to a Mini DisplayPort via these adaptors may have resolution problems or not "wake up" from sleep.
- While the DisplayPort specification can support digital audio, the older 2009 line of MacBooks, MacBook Pros, and Mac Minis cannot provide an audio signal through the Mini DisplayPort, and only do so over USB, Firewire, or the audio line out port. (The April 2010 line of MacBook Pro, and July 2010 iMac and later do support this). This can be a problem for users who want to connect their computers to HDTVs using a Mini DisplayPort to HDMI adapter. To work around this issue, some third-party manufacturers have created dual or triple-headed adapters that get power for the adapter from a USB port, video from the Mini DisplayPort, and audio from either the USB port or the optical-out port. Either option terminates with a single female HDMI connector, thus allowing both video and audio to be channeled over the single HDMI cable.

Adoption
- In early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification.
- In the fourth quarter of 2009, VESA announced that the Mini DisplayPort had been adopted. All devices using the Mini DisplayPort must comply with the 1.1a standard.
- On 7 January 2010, Toshiba introduced Satellite Pro S500, Tecra M11, A11 and S11 notebooks featuring Mini DisplayPort.
