'Adriatic Guard' or 'Adriatic Sentinel') was a volunteer organisation founded in 1922 in Split, in the recently established Kingdom of Serbs, Croats and Slovenes (later renamed Yugoslavia).

The Jadranska straža's adherence to the state ideology allowed it to remain active even after introduction of the 6 January Dictatorship in 1929.

They gradually shifted to criticising the government while placing a greater emphasis on Dalmatian and Croatian aspects of Adriatic orientation than on pan-Yugoslav themes.

The journal printed maritime-related material, including literary texts, scientific papers, current events, and coverage of topics related to fishing and tourism.

[1] Following the 1918 Armistice of Villa Giusti and the Austro-Hungarian surrender,[2] Italian troops moved to occupy parts of the Eastern Adriatic shore promised to Italy under the Treaty of London, ahead of the Paris Peace Conference.

[3] The Kingdom of Serbs, Croats and Slovenes (later renamed Yugoslavia), established shortly after the war, laid a competing claim to the eastern Adriatic to counter the Italian demands.

[4] The problem of establishing the border between Italy and Yugoslavia—known as the Adriatic question—and the future status of Rijeka became major points of dispute at the Paris Peace Conference.

[8] Jadranska straža was established in Split at a public rally held at the present-day Prokurative [hr] square on 19 February 1922.

[9] The organisation's stated objectives were the promotion of military, commercial and cultural interests of Yugoslavia in the Adriatic Sea and along its shores.

Its activities, including publishing periodicals, tourist guide books and support for scientific research, were aimed at fostering love for the Adriatic Sea.

Ultimately, Jadranska straža intended to influence public opinion, promoting the perspective that the Adriatic Sea was essential to the country and defining the nation's identity and attempting to align the objectives with the ideology of integral Yugoslavism.

[10] Through pursuit of those objectives, Jadranska straža aimed to support economic and cultural development of the Adriatic region and work towards reclaiming the territories awarded to Italy through the Treaty of Rapallo.

[18] The membership fee varied as discounted rates were charged to different groups of members such as workers, peasants, soldiers, children, etc.

[23] Jadranska straža enjoyed a particularly close relationship with the Ministry of the Army and Navy and its membership included generals and admirals.

[25] Members of the organisation living in Dalmatia expected the state to pursue vigorous economic development of the region and the entire Adriatic coast.

Despite Jadranska straža's lobbying efforts, the national government continued to prioritise routes of transportation oriented to the Port of Thessaloniki in Greece.

[26] This was at least in part due to lack of rail connections between Dalmatia and the rest of the country and challenging terrain in the coastal hinterland.

[26] Beginning in 1934, the central office directed its branches to organise activities, placing a greater emphasis on Dalmatian and Croatian aspects of Adriatic orientation than on pan-Yugoslav themes, and Tartaglia endorsed the 1934 Zagreb Memorandum crtiticising the central government for neglecting Croatian political and cultural demands.

At the same time, Jadranska straža gave full support to establishment of Banovina of Croatia as a vehicle for realising Croatian political demands.

[36] The organisation's publications included guide books for Dubrovnik, the Bay of Kotor, Split, Trogir, Hvar and Vis, and the northern Adriatic.
