Kotati was a planet contacted by USS Voyager in 2372 in its subspace communications logs.

Neelix skimmed over this communication while looking for "something anomalous" in the logs, noting the transmissions in the log from "Voyager to Mithren... Mithren again... Voyager to Kotati..." (VOY: "Investigations")

Both and the Star Trek Encyclopedia (4th ed., vol. 1, p. 440) identified it as a Delta Quadrant planet. The Star Trek: Star Charts (p. 84) depicted it as a star system with a F-class star. Voyager contacted this system on stardate 49485.
