Dorothea Weber, née Le Brocq, who died in 1993, is being awarded the prestigious honour of Righteous Among Nations.
There will be a special ceremony at 11:15 at the Tapestry Museum on the New North Quay and a plaque will be unveiled afterwards at No. 7 West Park Avenue.
Mrs Weber hid her friend Hedwig Bercu from German soldiers for 18 months.
The ceremony will be attended by the Bailiff, William Bailhache, His Excellency the Lieutenant-Governor Genral Sir John McColl and Chief Minister Ian Gorst.
Mrs Weber is the second Channel Islanders to receive the honour. Albert Bedane was given posthumous recognition for helping among others Dutch Jewess Mary Richardson who he hid for over two and a half years during the Occupation.
His name is now inscribed in the Avenue of the Righteous Gentiles at the Yad Vashem memorial in Jerusalem as ‘Righteous among the Nations’, Israel’s highest Holocaust honour.
The medal was presented to his grandson in London and is now on permanent display at the Maritime Museum.
