Helwan Governorate (Arabic: ‏محافظة حلوان‎ Muḥāfaẓat Ḥilwān) was one of the governorates of Egypt. It was located in Lower Egypt.

The Helwan Governorate was split from the Cairo Governorate in April 2008. It was created through a presidential decree in order to ease the burden placed on Cairo, one of Egypt's most densely populated governorates. The city of Helwan became the capital of the Helwan Governorate, which encompassed most of the eastern suburbs of Cairo, notably the affluent neighbourhood of Maadi. In April 2011, Prime Minister Essam Sharaf abolished the Helwan Governorate and reincorporated its territory into the Cairo Governorate.

Helwan (Arabic: حلوان‎ Ḥilwān), also spelled Hilwan or Hulwan or Holwan, is a city in Egypt on the bank of the Nile river, opposite the ruins of Memphis. Originally a southern suburb of Cairo, it served as the capital of the now defunct Helwan Governorate from April 2008 to April 2011, after which it was re-incorporated into the Cairo Governorate. The kism of Helwan had a population of 643,327 at the 2006 population census.

The Khedivial Astronomical Observatory was built here 1903-1904, and was used to observe Halley's comet. Egypt's oldest and largest private psychiatric clinic, the Behman Hospital, was also constructed here in 1939.

During the early part of the 20th century, the city was the site of RAF Helwan, a major British airbase, which was later used by the Egyptian Air Force.

In April 2008, the Helwan Governorate was split from the Cairo Governorate. It encompassed most of the suburbs, new compounds and villages located in the southern part of Cairo. The city of Helwan became the capital of the new governorate. Following the dissolution of the Helwan Governorate in April 2011, the city of Helwan was reincorporated into the Cairo Governorate.
