小瓜帽 (zucchetto,众数写法 zucchetti)，是天主教和圣公宗高级圣职人员所戴的小圆帽。教宗用白色，枢机用红色，主教用紫色，总院长、神父用黑色。在弥撒时具主教级者，除了在感恩经外，都戴着这种帽子。

是由八片布缝合而成，上加一根帽茎，因形似南瓜而得名。另一种说法是在其功能，以为过去需要削发的圣职人员的头保暖。

第二次梵蒂冈大公会议礼仪改革前，成为神职人员必须接受剪发礼，在头顶上剪一圆圈，故戴小瓜帽以御寒。现今剪发礼已取消，小瓜帽则演变成了礼仪服饰。

The zucchetto (/tsʊˈkɛtoʊ/; Italian pronunciation: [dzukˈketto; tsuk-]; meaning "small gourd", from zucca, "pumpkin") is a small, hemispherical, form-fitting ecclesiastical skullcap worn by clerics of various Catholic Churches, the Syriac Orthodox Church, and by the higher clergy in Anglicanism. The plural is zucchetti; it is also known by the names pilus, pilos, pileus, pileolus (pileolo), subbiretum, submitrale, soli deo (solideo), berrettino, calotte (calotta).
