Lieutenant Kaplan was a 23rd century Starfleet security officer serving aboard the Federation starship USS Enterprise under Captain James T. Kirk.

In 2267, Kaplan was among the landing party of nine that was surveying the planet Gamma Trianguli VI. Kaplan was vaporized when he was struck by lightning during an electrical storm created by Vaal, the computer that controlled the planet's climate.

Kirk later lamented Kaplan's death, stating that he knew Kaplan's family. (TOS: "The Apple")
