Okhla is an urban neighbourhood located near the Okhla barrage in the South East Delhi district of Delhi near the border between Delhi and Uttar Pradesh. Okhla has lent its name to the nearby planned township of New Okhla Industrial Development Authority or NOIDA. Okhla is also an assembly constituency.

The Okhla barrage is a 791 meters or roughly 800-yard long weir across Yamuna River opened in 1874. It also serves as the location of Okhla Bird Sanctuary today. It is situated 10 km to the south of New Delhi and downstream of Nizamuddin bridge at Okhla, where Agra canal originates from it. The top of barrage also serves as the Delhi-Noida carriageway of Kalindi Kunj-Mithapur road. Nearby later-era New Okhla Barrage is 554 meters long.
