Abstract.We study intuitionistic H-fuzzy relations on an intuitionistic H-fuzzy sets in a categorical point of view. In particular, we show that the category ${\bf IFRel} (H)$ is (co)topological, catesian closed and final episinks in ${\bf IFRel} (H)$ are preserved by pullbacks. Also, we show that the subcategory ${\bf IFRel_{R}}(H)$ of ${\bf IFRel} (H)$ has the same properties as ${\bf IFRel} (H)$.
