图尔库（芬兰语：Turku，又译土库，瑞典语：Åbo，译作奥布），位于芬兰西南部，是该国第五大城市，也是最古老的城市（在1154年已有记载），人口174,825人（2004年）。

图尔库是芬兰第一个首都（1812年以前），也是第一个教区（成立于1300年，后来成为大主教区），还是芬兰第一所大学 （建于1640年）的所在地。

1741年瑞典王国进攻俄罗斯帝国，企图夺回芬兰湾地带，但俄军占领了芬兰全境。1743年，瑞典屈辱求和，俄国迫使之签定奥布和约，割让包括维堡在内的芬兰东南部地区。

Turku (Finnish pronunciation: [ˈturku]; Swedish:Åbo [ˈoːbʊ]) is a city on the southwest coast of Finland at the mouth of the Aura River, in the region of Southwest Finland. Turku, as a town, was settled during the 13th century and founded most likely at the end of the 13th century, making it the oldest city in Finland. It quickly became the most important city in Finland, a status it retained for hundreds of years. After Finland became part of the Russian Empire (1809) and the capital of the Grand Duchy of Finland was moved to Helsinki (1812), Turku continued to be the most populous city in Finland until the end of the 1840s, and it remains a regional capital and an important business and cultural center.
