Maneka Gandhi v. Union of India (1978) is a landmark case in the Indian constitutional law that expanded the scope of Article 21 of the Indian Constitution. The case dealt with the question of whether the right to life and personal liberty, as guaranteed by Article 21, included the right to travel abroad.

The case arose after the Indian government passed an order revoking Maneka Gandhi's passport, preventing her from traveling abroad. Gandhi challenged the order, arguing that it violated her fundamental right to life and personal liberty as guaranteed by Article 21 of the Indian Constitution.
