Teesmouth Lifeboat Station was a Royal National Lifeboat Institution (RNLI) lifeboat station, situated on the mouth of the River Tees, South Gare, North Yorkshire, England. The lifeboat station had been operating at Teesmouth for 177 years when it was closed by the RNLI in 2006. The withdrawal of the lifeboat capability from Teesmouth was subject to much criticism from the local council and the volunteers who crewed the boat, but the RNLI stated that there was an over-provision of lifeboat cover on the north-east coast.
