Royal Borough of Greenwich twinned administrative body Maribor
– Reinickendorf, Berlin, Germany (since 1965). The initiative of the twinning with this Berlin borough dates from the times of the Metropolitan Borough of Woolwich. A London telephone box and a red pillar box beside Lake Tegel were gifted by Greenwich borough. A Berlin Buddy Bear in General Gordon Square (Woolwich) commemorates the 50th anniversary of the twinning.
 – Maribor, Slovenia (since 1966). The 50th anniversary of the town twinning with Slovenia's second largest city was celebrated with a ballet performance in Woolwich Town Hall and the revealing of a plaque in the renamed Maribor Park in the Royal Arsenal.
 – Tema, Ghana (since 2000). The town twinning with Tema has led to the opening of Tema's first Information Technology Centre (by the Duke of Edinburgh in 2000), the gifting of a mobile ICT learning centre to Tema (2005), the shipping of a converted Greenwich council passenger services bus, packed with books for school libraries and second-hand computers, as well as regular youth exchanges between Greenwich and Tema.
