The Lord Protector's people are a group of Pegasus galaxy humans who live on the Lord Protector's Planet.
They were under the control and protection of the Tower until the Lord Protector died and the Zero Point Module was depleted. (SGA: "The Tower")
In the American Mythology comics, while AR-1 visited their planet for a replacement control crystal, the Protector's people where attacked by aliens. Ronon Dex and Dr. Daniel Jackson helped evacuate them, and Dr. Rodney McKay and John Sheppard raised the people's buried City-ship from the ground and powered shields.
Later, Lord Protector Tavius and his people were evacuated to the Daedalus and were housed in the starboard bay. (SGA: "Gateways 1", "Gateways 2")
