Mesaieed (Arabic: مسيعيد, romanized: Musaī'īd, also transliterated as Umm Sa'id) is an industrial city in Al Wakrah Municipality 36 kilometres (22 mi) south of the Qatari capital Doha.

It was one of the most important cities in Qatar during the 20th century, having gained recognition as a prime industrial zone and tanking center for petroleum received from Dukhan.

[3] According to The Centre for Geographic Information Systems of Qatar, the city derives its name from a plant known locally as "sead" which previously grew in bountiful quantities in the area.

It was chosen by the company because of its proximity to the working population in Doha and Al Wakrah and because of the depth of its waters.

Sheikh Khalifa bin Hamad Al Thani, in his correspondence with the British, stated he believed the redundancies to be justified and thus did not support the workers' right to strike.

Despite one or two incidents involving confrontations between strikers and senior staff of Qatar Petroleum, the strike largely remained peaceful.

Fearful that the strike would spread to Qatar's other industrial city of Dukhan, Sheikh Khalifa sent a force of 40 policemen to Mesaieed that month.

[8] The development of Mesaieed faced some limitations in its early years: the encroaching industrial area to the south, sand dunes and an energy corridor to the west, and a sabkha (a type of salt flat) to the east.

[9] The initial structure plan for Mesaieed envisioned five distinct neighborhoods, each with its own center, delineated by primary and secondary roads.

These neighborhoods were designed to feature unique identities and local centers to meet daily needs, promoting both automobile and pedestrian movement.

By the mid-1970s, it became clear that there was a pressing need for more residential accommodation to support the rapidly growing Mesaieed Industrial Area.

At that time, Mesaieed was equipped with essential services and amenities, including a health center, police and fire stations, a post office, two banks, a bakery, a cold store, two primary schools, an international school, staff clubs, mosques, a cinema, and a golf course.

After QatarEnergy transferred its headquarters from Dukhan to Mesaieed in 1956, they undertook substantial development on workers' camps and facilities.

[11] The rapid growth of oil and natural gas revenues in the 1960s and the accession of Khalifa bin Hamad Al Thani in 1972 resulted in the government assuming a portion of control over the area.

[20] Mesaieed is located on the southeast coast, approximately 36 kilometres (22 mi) south of Qatar's capital, Doha.

[21] Mesaieed forms the eastern boundary of the southern desert region, which occupies 34.7% of Qatar's total area.

Of the four sub-regions of the southern desert, Mesaieed is a part of the trapezoidal-shaped hamada sub-group, which has its western boundary at Abu Nakhla, the water pipeline running between the two demarcating the base of this zone.

The surface is covered by a mosaic of closely packed pebbles and rock fragments or, in some places, by a thin layer of indurated mineral deposits forming a hard crust.

[23] To the northeast of the coast, where the residential section is located, there are sandy hillocks which lie 9 m above sea level.

The industrial area's strategic location and the high water table help ensure that Mesaieed's groundwater remains unpolluted.

[28] Common vegetation found in Mesaieed include reeds (Phragmites australis) in wet areas,[29] desert thumbs (Cynomorium coccineum) near the coast,[30] the damas tree (Conocarpus lancifolius) near the industrial area,[31] nafayj (Pulicaria gnaphalodes) in depressions and wadis,[32] and shanan (Soda rosmarinus) on sand dunes and sabkhas.

[43] In 2012, Barwa Group launched a construction project in the southern zone of Mesaieed to establish a large tourist resort over an area of 829 square metres (8,920 sq ft).

[44] Al Afjah Heritage Village is a cultural attraction located on the western boundaries of Mesaieed.

It is the most sizable club in Mesaieed and hosts many recreational facilities such as a main hall, a football ground, tennis and basketball courts, a swimming pool and restaurants.
