《我的太阳》（意大利语：'O sole mio），是一首创作于1898年的那不勒斯（拿波里）歌曲。这首歌曲流传之广，不仅是知名男高音如恩里科·克鲁索（Enrico Caruso）、卢奇亚诺·帕瓦罗蒂（Luciano Pavarotti）、安德烈·波切利（Andrea Bocelli）等的保留曲目，也被诸如布莱恩·亚当斯等流行摇滚艺人演绎。作词Giovanni Capurro，作曲Eduardo di Capua，尽管该首歌词已被翻译成多种语言，但多数时候还使用拿坡里方言演唱。

「O sole mio」的字面翻译即是我的太阳（非“啊!我的太阳”），其中「O」只是冠词。

Its lyrics were written by Giovanni Capurro and the music was composed by Eduardo di Capua.
