The Senate () is one of the two chambers of the bicameral Guinean Parliament established in the 2025 constitution in the unitary state of Guinea.
The Senate has 87 members. Two-third of the members are indirectly elected by an electoral college by local councillors. One-third of the members are appointed by the President of Guinea. The members serve a six-year term.
The Senate is less powerful than the lower chamber, National Assembly, and can affect only certain areas of legislation.
The Senate is expected to get organized after the 2026 elections.
