A conference room was a location where meetings and similar gatherings were held.
While the Interspecies Medical Exchange was hosting a conference at a facility on the surface of Dekendi III in 2152, an area of the building which was reserved for a Vulcan contingent included a Vulcan conference room. At one point during the IME conference, this room was used for a hearing attended by not only Vulcan doctors Strom, Oratt and Yuris but also Enterprise captain Jonathan Archer and Vulcan Subcommander T'Pol. The hearing mainly regarded Pa'nar Syndrome and T'Pol having recently been recalled to Vulcan due to concerns over the fact she had contracted the syndrome. However, Dr. Yuris also took the opportunity to concede several revelations, including that he also had Pa'nar Syndrome and that T'Pol was not responsible for having initiated the Vulcan mind meld that had led her to acquire the affliction.

In 2366, Captain Jean-Luc Picard ordered the senior staff to the conference room to discuss a series of computer malfunctions occurring on the USS Enterprise-D. (TNG: "Evolution") The conference room on Galaxy-class starships is located on deck 1, directly behind the main bridge.
Following their arrival at Starbase 375 aboard the IKS Rotarran, Captain Benjamin Sisko and his senior staff were asked to beam directly to the starbase's conference room to be debriefed by Admiral William Ross on their successful mission destroying a Dominion ketracel-white facility.
