The Tseung Kwan O-Lam Tin Tunnel () is a tunnel in Hong Kong that is part of Route 6. Originally expected to open in 2021, its opening was delayed to 11 December 2022 due to the worldwide outbreak of COVID-19.
The tunnel connects Lam Tin to the Tseung Kwan O New Town. The eastern edge of the tunnel project connects directly with the Cross Bay Link to LOHAS Park.
