Jaan Poska VR III/1 was an Estonian barrister and politician.

The Estonian Cross of Liberty is a military decoration established by the Prime Minister of Estonia, Konstantin Päts, on 24 February 1919 to honor the people for their services during the Estonian War of Independence. The Estonian Cross of Liberty has three divisions, each in three classes. Division I was granted for military leadership, division II for personal courage and division III for civilian services. The division and class of the Estonian Cross of Liberty is usually added to the name of the recipient in the form of post-nominal letters. The 1st class of the II division of the Estonian Cross of Liberty was never granted. Although still mentioned in the list of Estonian state decorations by the president of the republic, the bestowal of the Estonian Cross of Liberty was terminated on 19 June 1925.
