圆规座（英語：Circinus）是既細小又黯淡的南半天球星座，最初由法國天文學家尼可拉·路易·拉卡伊於1756年創立。英語名字為“圓規”一詞的拉丁語，這個星座代表的是繪圖中用於畫圓的圓規。圓規座內最亮的恆星是圓規座α，視星等為3.19。它是一顆變化輕微變星，同時是夜空中最亮的快速振蕩Ap星。圓規座AX是一顆肉眼可見的造父變星，而則是一顆被認為是由兩顆白矮星合併而成的黯淡恆星。圓規座內有兩顆與太陽類似且擁有行星系統的恆星：HD 134060擁有兩個小的行星，HD 129445則擁有一顆與木星類似的行星。超新星SN 185於公元185年在圓規座出現，現存有中國觀察者的記錄。在最近的20世紀圓規座內還出現過兩顆新星。銀河橫穿圓規座，當中的顯著天體有疏散星團NGC 5823和行星狀星雲NGC 5315。圓規座內有一個值得注意的螺旋星系——圓規座星系，它於1977年被發現，是最接近銀河系的西佛星系。在1977年被發現的還有（ACI），它是從圓規座輻射出去的流星雨。
