Omar Hayat Mahal (Urdu: عمر حیات محل), also spelt Umer Hayat Mahal, and alternatively known as Gulzar Manzil, is an early 20th-century wooden haveli mansion in Chiniot, Pakistan. Construction of the mansion was started in 1923, and completed by 1935.
The mansion, originally 5-storeys tall, was built by Sheikh Omar Hayat – a Chinioti businessman who had made his fortune in Calcutta. The edifice displays outstanding examples of Chiniot's local woodworking craftsmanship, and has been described as an "ornament" of a building on account of its lavishly decorated interior.
