鲁拜集（波斯语：رباعیات）又译《柔巴依集》，是波斯11世纪的诗人欧玛尔·海亚姆的四行诗集。四行诗的特征是每首四行，一、二、四行押韵，第三行通常不押韵，这和我国古代的绝句比较相似。现在的版本通常是爱德华·非茨格拉德的英文译本。

The Rubáiyát of Omar Khayyám (Persian:رباعیات عمر خیام‎‎) is the title that Edward FitzGerald gave to his translation of a selection of poems, originally written in Persian and numbering about a thousand, attributed to Omar Khayyám (1048–1131), a Persian poet, mathematician, and astronomer. A ruba'i is a two-line stanza with two parts (or hemistichs) per line, hence the word rubáiyát (derived from the Arabic language root for "four"), meaning "quatrains".
