四氫吡喃（THP）是由一個(gè)含有五個(gè)碳原子和一個(gè)氧原子的飽和六元環(huán)組成的有機(jī)化合物。它被命名為吡喃，它包含兩個(gè)雙鍵，并且可以通過添加四個(gè)氫而產(chǎn)生。在2013，其優(yōu)選的IUPAC名稱被確立為OxAn?；衔餅闊o色揮發(fā)性液體，但不清楚。然而，四氫吡喃衍生物更為常見。由醇和3,4-二氫吡喃反應(yīng)得到的2-四氫吡喃(THP-)醚在有機(jī)合成中通常用作保護(hù)基。此外，四氫吡喃環(huán)體系，即五個(gè)碳原子和一個(gè)氧，是吡喃糖如葡萄糖的核心。在氣相中，THP存在于其最低能量Cs對稱椅構(gòu)象中。
