Mac OS X Server 1.0 is an operating system developed by Apple Computer. Released on March 16, 1999, it was Apple's first commercially released operating system derived from NeXTSTEP following its acquisition of NeXT in 1997, and preceded the release of the consumer version of Mac OS X by two years. It was marketed as an integrated server operating system and included Apple File Services, Macintosh Manager, the Apache HTTP Server, WebObjects, NetBoot, and QuickTime Streaming Server.

Mac OS X Server 1.0 was based on Rhapsody, Apple's NeXTSTEP-based operating system that was intended to replace the classic Mac OS. It combined elements of Apple's Platinum appearance with the NeXTSTEP interface. It supported applications written for the OpenStep APIs ("Yellow Box") and existing Mac OS applications running within an emulated Mac OS 8 environment ("Blue Box").

Mac OS X Server 1.0 was succeeded by Mac OS X Server 10.0 in May 2001.
