Sinop is an electoral district of the Grand National Assembly of Turkey. It elects two members of parliament (deputies) to represent the province of the same name for a four-year term by the D'Hondt method, a party-list proportional representation system.

Population reviews of each electoral district are conducted before each general election, which can lead to certain districts being granted a smaller or greater number of parliamentary seats. The number of seats allocated to Sinop has gradually fallen over the last half-century from a high of six in the 1950s to just two seats today.
