象限仪座(拉丁语:mural quadrant)是法国天文学家热罗姆·拉朗德于1795年创建的星座。它描绘了一个挂在墙上的四分仪(象限仪),他和他的侄子Michel Lefrançois de Lalande用它绘制了天球图,并在法国地图册中被命名为《Le Mural 》[1]。它位于牧夫座和天龙座之间,靠近大熊座的尾部[2],包含介于七公增七(牧夫座β)和摇光(大熊座η)之间的恒星[3]。
约翰·波德将其名称改为拉丁语: Quadrans Muralis,并在1801年的《Uranographia》星图中将星座缩小了一点,以避免与邻近的星座发生冲突[1]。Quadrans Muralis was omitted
在1922年,象限仪座被国际天文学联合会正式确定其官方认可的星座清单时,废弃了象限仪座[4]。
