眼镜蛇瓶子草（学名：Darlingtonia californica），又称为加州瓶子草（California Pitcher plant）、眼镜蛇百合（Cobra Lily）、眼镜蛇植物（Cobra Plant），为瓶子草科眼镜蛇瓶子草属食虫植物。眼镜蛇瓶子草属为单种属，仅眼镜蛇瓶子草一种。其原产于奥勒冈州及加利福尼亚州以北的沼泽及冷水浸润地。

眼镜蛇瓶子草的种加词“californica”来源于其发现地加利福尼亚州。而眼镜蛇瓶子草属的学名来源于宾夕法尼亚州伯明翰植物学家、医生及政治家威廉·达林顿（William Darlington）。眼镜蛇瓶子草的中文名称来源于其类似于眼镜蛇的管状叶及其类似蛇信子的管状叶末端叉状部分。
