The 1989–90 ECHL season was the second season of the ECHL. The league brought back all five teams from the inaugural season and added three more franchises in Greensboro, North Carolina, Nashville, Tennessee, and Norfolk, Virginia. Before the season began, the Carolina Thunderbirds changed their name to the Winston-Salem Thunderbirds. The eight teams played sixty games in the schedule, unchanged from the total games played in the inaugural 1988–89 ECHL season. The Winston-Salem Thunderbirds finished first overall in the regular season. The Greensboro Monarchs won their first Riley Cup championship.
