塞普丁修拉共和国（希腊语：Επτάνησος Πολιτεία），又译为七岛共和国，为1800年至1807年间由爱奥尼亚中7个主要岛屿组成的一个希腊人自治国家，名义上隶属于奥斯曼帝国，实际为俄罗斯控制。

自17世纪以来，爱奥尼亚群岛一直属于威尼斯共和国。1797年，根据法国将领拿破仑·波拿巴和奥地利签订的《坎波福尔米奥条约》，威尼斯共和国被两国瓜分，爱奥尼亚群岛从而归属于法国统治下。受到法国大革命的鼓舞，当地人民热烈欢迎法国军队的到来，并宣布接受1795年法国宪法，希望能以此推翻外来贵族的压迫。但是，岛民们很快发现法国占领当局对他们课以重税，而且法军士兵屡次在当地发生不轨行为，于是他们开始反抗法国占领者。

The Septinsular Republic (Greek:Ἑπτάνησος Πολιτεία, Italian:Repubblica Settinsulare, Ottoman Turkish:جزاييرى صباى موجتميا جومهورو‎ Cezayir-i Seb'a-i Müctemia Cumhuru) was an island republic that existed from 1800 to 1807 under nominal Russian and Ottoman sovereignty in the Ionian Islands. It succeeded the previous French departments of Greece. It was the first time Greeks had been granted even limited self-government since the fall of the last remnants of the Byzantine Empire to the Ottomans in the mid-15th century. In 1807, the republic was ceded to Napoleon's First French Empire, but the islands were not annexed by France, keeping their institutions of government (known in French as République Septinsulaire or République des Sept-Îles). The British gradually took control of the islands, and following the Treaty of Paris, the islands were formally organised into the United States of the Ionian Islands under British protection.
