卜卦占星术（Horary Astrology）是占星术的一个古老的分支，它可以让占星术家用一张由精确时间所画的星图来回答问题，也可以看出问卜者对于问题最关心的部分，或是问题何时会发生。问题的答案可能只是简单的是或否，但通常都会比表面上所见还复杂的多，例如牵涉到问卜者的动机和他们的选择的时候。

卜卦占星术有一套自己的严格规则。例如月亮在星图中是最重要的，第一宫代表问卜者，还有行星和宫头之间的角度也比在其他占星术中重要（就算是问题征象宫的宫主星而已经预先分析过了，也是一样）。其他卜卦占星术中所使用的关键因素还有月交点（月亮轨道和黄道的交点）或是阿拉伯点等。

Horary astrology is an ancient branch of horoscopic astrology in which an astrologer attempts to answer a question by constructing a horoscope for the exact time at which the question was received and understood by the astrologer.

The answer to the horary question might be a simple yes or no, but is generally more complex with insights into, for example, the motives of the questioner, the motives of others involved in the matter, and the options available to them.
