St. John's Lodge No.80 is a Lodge of Freemasons meeting at the Wearside Masonic Temple. The Lodge meets on the 2nd Tuesday, September to May, excluding January. The Installation meeting is in December.

The Lodge has been warranted since 21st October 1761 on the register of Antient Grand Lodge of England. The Lodge was formed at a time when the 2nd Regiment, Royal Lancashire Militia was stationed in Sunderland by members of a military Knights of Malta Lodge. 

St. John's Lodge constructed the Masonic Hall in Park Terrace, Sunderland, before moving to Wearside Masonic Temple in 1932. The Park Terrace building facade was transported, brick by brick, to Beamish Museum where it now stands in the 1900s town.

Visiting brethren will be made most welcome and are advised to contact the Lodge Secretary in advance with regards to dining.
