Yerdrin Lek was an Yridian information dealer during the 22nd century.
In an alternate timeline where the Xindi destroyed Earth, Yerdrin Lek was hired by the Xindi to help find the last colony of Humans. They paid him to follow Doctor Phlox when he left Denobula, which he did in 2165 to treat Jonathan Archer. Lek tailed Phlox to the Ceti Alpha system, and informed the Xindi of its location. He was captured and interrogated by Starfleet officers aboard Enterprise NX-01 (where he tried to pose as a dealer in Rigelian flamegems). However, it was too late and, following his signal, the Xindi attacked Ceti Alpha. Lek presumably died in Enterprise's brig when the ship was destroyed in a subspace implosion which negated this timeline. (ENT: "Twilight")
