Ras Abu Fontas (Arabic: راس بو فنطاس) is a coastal industrial area in Doha on the boundary with Al Wakrah Municipality in Qatar. The government has designated the district as a free economic zone starting in 2019.

In a 2010 survey of Ras Abu Fontas' coastal waters conducted by the Qatar Statistics Authority, it was found that its average depth was 2.75 meters (9 ft 0 in) and its average pH was 7.84. Furthermore, the waters had a salinity of 49.61 psu, an average temperature of 22.51 °C and 26.13 mg/L of dissolved oxygen.

Ras Abu Fontas A was inaugurated in April 1977 at a cost of QR 2.1 billion. In 1983, its 14 gas turbines had a capacity of 618 MW. As of 2018, this capacity has been lowered to 497 MW.

Ras Abu Fontas B power station was commissioned in the 1990s. Daily capacity is currently 609 MW. After an expansion was announced, Ras Abu Fontas B1 power station was officially opened in July 2001, costing nearly QR 780 million. This added 377 MW to the plant's capacity. Capacity was increased by 567 MW with the addition of Ras Abu Fontas B2.

In 1981, the Qatari government installed eight desalination units in Ras Abu Fontas A, with each unit possessing a daily capacity of 4 million gallons. This capacity was eventually raised to 55 million gallons per day. The introduction of Ras Abu Fontas A1 saw daily capacity increased by 45 million gallons.

Ras Abu Fontas A2 desalination plant was opened in November 2015 after being constructed at a cost of over QR 1.8 billion. It had a daily capacity of 36 million gallons.

In September 2016, Ras Abu Fontas A3 desalination plant became operational, having been opened at a cost of QR 1.75 billion. Capacity was 22 million gallons per day, but after being expanded in April 2017, its capacity was raised to 36 billion gallons per day.

Ras Abu Fontas B and Ras Abu Fontas B2 raised capacity by 33 million and 30 million gallons per day, respectively.
