留學(xué)，舊稱留洋，是由留學(xué)生一詞省略而來(lái)的，一般是指一個(gè)人去母國(guó)以外的國(guó)家接受各類教育，時(shí)間可以為短期或長(zhǎng)期(從幾個(gè)星期到幾年)。在中國(guó)大陸，學(xué)生把前往香港、澳門(mén)等地區(qū)的學(xué)習(xí)也稱為留學(xué)，這是由于這些地區(qū)有著不同的教育制度。另外，美國(guó)等國(guó)家組織的一類海外短期的交換學(xué)生計(jì)劃，其英文名字“Study abroad”直譯也為留學(xué)，中國(guó)大陸稱為海外交流。因?yàn)榱魧W(xué)國(guó)家和地區(qū)的不同，留學(xué)所需要的條件也不一樣。
