Waldviertel, also known as Electoral District 3B (German: Wahlkreis 3B), is one of the 39 multi-member regional electoral districts of the National Council, the lower house of the Austrian Parliament, the national legislature of Austria.

[6] Waldviertel currently elects five of the 183 members of the National Council using the open party-list proportional representation electoral system.

[10] In the first stage, seats are allocated to parties (lists) at the regional level using a state-wide Hare quota (wahlzahl) (valid votes in the state divided by the number of seats in the state).

[11][12] Electors may cast one preferential vote for individual candidates at the regional, state and federal levels.

[12][13] At the regional level, candidates must receive preferential votes amounting to at least 14% of the valid votes cast for their party to over-ride the order of the party list (10% and 7% respectively for the state and federal levels).
