'यज्ञ' संबंधी विधि-विधानों का पता यजुर्वेद से चलता है। यजुर्वेद के दो भाग हैं-शुक्ल यजुर्वेद तथा कृष्ण यजुर्वेद।

Yajurveda in Sanskrit means ‘wisdom of sacrificial formulas.’ This Veda, compiled a century or two after the Rig-veda, contains prose and verse formulae that were to be pronounced by the priests performing the manual part of the sacrifice. It describes in prose about the procedural details of performing different rituals and Yajnas using the hymns of the Rigveda. The Samhitas of Yajurveda are divided into two parts: Shukla or white Yajurveda and Krishna or black Yajurveda.
