The Democratic Organisation for Kayan National Unity (; DOKNU) was a political party in Myanmar.
Following the reintroduction of multi-party democracy after the 8888 Uprising, the party contested three seats in the 1990 general elections. It received 0.12% of the vote, winning two seats; U Khun Marko Ban in Pekhon and U R.P. Thaung in Thandaung.
The party was banned by the military government in 1992. Party members later established the Kayan National Party.
