Tingwall, (Old Norse: Þingvöllr = Field of the Thing assembly) is a hamlet and parish in Shetland, mostly on Mainland. The hamlet lies about 4 miles north west of Lerwick. It is at the head of a long narrow bay. Tingwall Airport is here.
Tingwall parish includes the settlements of Scalloway, Whiteness, Veensgarth and Gott, and the Vallafield housing estate. The centre of the parish was the Tingwall Kirk. It comprehends a section of Mainland, stretching from the Atlantic at Scalloway, to the North Sea at Rova Head and includes the formerly inhabited islands of Hildasay, Langa, Linga, and Oxna. 
The Mainland section is divided into two districts by a hill ridge, and comprises two parallel valleys (nearly at right angles from the ridge). The Tingwall valley extends north from near Scalloway to the south end of Lax Firth. It is diversified by the lochs of Tingwall, Girlsta, Asta, Strom and some others.
It is so indented by the sea as to contain no point farther than two miles from it. Measured across marine intersections, it has a length of about nineteen miles, and a maximum breadth of ten miles.
The small promontory at the end of Tingwall Loch, known as Tingaholm or Law Ting Holm was once home to Shetland's earliest parliament. It was once an islet entirely surrounded by water and accessed by a stone causeway. In the 1850s the level of the loch was lowered, and the holm took on its present form.
Tingwall was also the base of the Archdeaconry in Shetland. The present day church lies on the site of a much older building, originally dedicated to St Magnus. The burial vault in the churchyard is believed to belong to this bearlier building, which is thought to have had a round tower, similar to that of the St Magnus Kirk on Egilsay, Orkney.
There are a number of ancient and historical monuments in Tingwall, including a standing stone  known as the murder stone. This stone is traditionally said to be the site where the Earl of Orkney killed his cousin in a power struggle over Shetland. Local folklore also suggests that a person could escape punishment at the Thing if they were able to run to the stone and claim sanctuary. Other versions of this story involve running to the Kirk, or the nearby croft at Griesta.
Tingwall was the home of brothers Laurence I. Graham (Lollie) and John J. Graham, two of Shetland's most influential 20th Century Writers.
