Apastamba Dharmasutra

''Āpastamba Dharmasūtra'' (Sanskrit: आपस्तम्ब धर्मसूत्र) is a Sanskrit text and one of the oldest Dharma-post vedic smriti related texts of Hinduism that have survived into the modern age from the 1st millennium BCE. It is one of three extant Dharmasutras texts from the Taittiriya school which is relatively newer in comparison to Maitrayaniya shakha of Krishna Yajurveda, the other two being ''Baudhayana Dharmasutra'' and ''Hiranyakesin Dharmasutra''.

The ''Apastamba Dharmasutra'' is part of ''Apastamba Kalpasutra'' collection, along with ''Apastamba Shrautasutra'' and ''Apastamba Grihyasutra''. One of the best preserved ancient texts on Dharma, it is also notable for mentioning and citing views of ten ancient experts on Dharma, which has led scholars to conclude that there existed a rich genre of Dharmasutras text in ancient India before this text was composed.
