Bindal is a municipality in the Helgeland region in the extreme southwest part of Nordland county, Norway. The administrative centre is the village of Terråk. Other villages include Bindalseidet, Holm, Vassås, Horsfjord and Åbygda.

The 1,266-square-kilometre (489 sq mi) municipality is the 81st largest by area out of the 357 municipalities in Norway. Bindal Municipality is the 306th most populous municipality in Norway with a population of 1,399. The municipality's population density is 1.2 inhabitants per square kilometre (3.1/sq mi) and its population has decreased by 10% over the previous 10-year period.

The ancient district of Bindalen belonged to Namdalen. However, in 1658, when the county (län) of Trondheim was ceded to Sweden in the Treaty of Roskilde, the status of the border district was ambiguous, with residents paying some taxes to Helgeland, in Nordland, and some to Namdalen. The decision was then made to redraw the county boundary to run down the Bindalsfjorden and assigning the northern part, Nord-Bindalen, to Nordland county (which remained in the Kingdom of Denmark-Norway) and the larger part remained in Trondheim county and became Sør-Bindalen (and part of the Kingdom of Sweden). The two remained separate after Trøndelag county was reunited with Norway in 1660.

In 1815, a single Church of Norway prestegjeld called Bindalen was created, combining Nord-Bindalen and Sør-Bindalen into one church parish, despite belonging to different counties.

The 1838 formannskapsdistrikt law divided the country into civil municipalities which were supposed to correspond to the parishes of the Church of Norway. The parish of Bindalen (which straddled the county border) was created as Bindal Municipality, but the southern part was part of Nordre Trondheim county and the northern part of the municipality belonged to Nordland county, making for an unusual situation. In 1852, the county border was moved so that all of Bindal Municipality was located in Nordland county.

On 1 January 1964, the area around the inner Bindalsfjorden and the village of Lande (population: 296) was transferred from Bindal Municipality to Brønnøy Municipality.

The municipality (originally the parish) is named after the Bindalen valley (Old Norse: Birnudalr). The first element is the genitive case of the river name Birna (now called the river Åbjøra). The river name is derived from the word birna which means "(female) bear". The last element is dalr which means "valley" or "dale". Historically, the name of the municipality was spelled Bindalen. On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Bindal, removing the definite form ending -en.

The coat of arms was granted on 9 February 1990. The official blazon is "Azure, six nails Or in annulo" (Norwegian: I blått seks gull nagler i rosett). This means the arms have a blue field (background) and the charge is a circular arrangement of six nails or rivets. The charge has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used. The blue color in the field symbolizes the importance of the sea and boating and the circular arrangement of rivets was chosen to symbolize the importance of the boat building industry in Bindal. There are six rivets to represent 6 school districts, 6 originally inhabited islands, and 6 fjords areas in the municipality. The arms were designed by Arvid Sveen.
