Order of the Cross of Terra Mariana

| post-nominals = Collar

The Order of the Cross of Terra Mariana (, also the Order of the Cross of St. Mary's Land) was instituted by the President of Estonia, Lennart Meri, on 16 May 1995 to honour the independence of the Estonian state. (The Latin name Terra Mariana, meaning the "Land of Mary" was the official name for Medieval Livonia and designated the area which includes what is now Latvia and southern Estonia in medieval times.)

The Order of the Cross of Terra Mariana is bestowed upon the President of the Republic. Presidents of the Republic who have ceased to hold office keep the Order of the Cross of Terra Mariana. The Collar of the Order was used de facto as the badge of office of the President of the Republic, since Soviet authorities took the original presidential collar, that of the Order of the National Coat of Arms, out of Estonia after the Soviet occupation of Estonia in 1940; it remains in the Kremlin in Moscow. A new collar of that order was made in 2008.

The Order of the Cross of Terra Mariana is also given as a decoration of the highest class to foreigners who have rendered special services to the Republic of Estonia. As such it is the highest and most distinguished order granted by Estonia to non-Estonian citizens.

Classes

The Order of the Cross of Terra Mariana comprises six classes:

• One special class – The Collar of the Cross of Terra Mariana;
• Five basic classes – 1st, 2nd, 3rd, 4th and 5th class.

The crosses and shields of all the classes of the Order of the Cross of Terra Mariana have the same design and are of the same size.

The blue colour tone of the moiré ribands belonging to the decorations of all the classes of the Order of the Cross of Terra Mariana is determined according to the international PANTONE colour-table as 300 C.
