GeoPort is type of proprietary serial port made by Apple computers but is now obselete. It was designed for video and voice applications and provided an interface between a telephone line or modem and a personal computer and was last used in the early 1990s.

GeoPort's features included improved telephone and fax service if used with Apple Telecom 3.0 as well a 2 Mbps bandwidth. It was appropriate for videoconferencing but was mainly used with analog phones which could not support sufficient line speed/bandwidth.

The GeoPort could be found on m-68K-based machines and earlier pre-USB Power Macintosh models. GeoPort technology is similar to the standard serial port but has a faster data transfer rate. This technology has largely been replaced with modem technology and support now which tends to be available through USB.
