The present invention relates to a controlled-release niacin formulation. In particular, the present invention relates to a controlled-release niacin formulation, comprising niacin; hydroxypropyl methylcellulose; and a carboxyvinyl polymer, in which the carboxyvinyl polymer and hydroxypropyl methylcellulose are contained in a predetermined weight ratio, and to a preparation method thereof. The controlled-release niacin formulation according to the present invention maintains its matrix shape until completion of release, and maintains its release pattern without fluctuation for a desired time period, unlike a commercial formulation. In particular, since niacin formulations are used for long-term treatment of hyperlipidemia, the controlled-release niacin formulation of the present invention, capable of maintaining effective blood concentration and high stability for a long period of time, is very useful.
