「血河」演说（Rivers of Blood speech）是英国保守党国会议员埃诺奇·鲍威尔于1968年4月20日发表的演说，内容是批评英联邦移民政策和反歧视立法。虽然鲍威尔本人称之为「伯明翰演说」，但普遍取其中引用埃涅阿斯纪的典故而称之为「血河」演说。「血河」一词并没有出现在演说中，只是出自其中一句话「展望前方之际，我满有预感；如同罗马人一般，我似乎看到了『台伯河冒起了血的泡沫』」（"As I look ahead, I am filled with foreboding; like the Roman, I seem to see 'the River Tiber foaming with much blood.'"）。

Enoch Powell's 20 April 1968 address to the General Meeting of the West Midlands Area Conservative Political Centre (commonly called "Rivers of Blood") was a speech criticising Commonwealth immigration and anti-discrimination legislation that had been proposed in the United Kingdom. Powell (1912–1998) was the Conservative Member of Parliament for Wolverhampton South West. Powell referred to the speech as "the Birmingham speech," but it is otherwise known as the "Rivers of Blood" speech, a title derived from its allusion to a line from Virgil's Aeneid. The phrase "rivers of blood" does not appear in the speech; the name alludes to the line, "As I look ahead, I am filled with foreboding; like the Roman, I seem to see 'the River Tiber foaming with much blood.'"
