A catalyst for dehydration reaction of hydroxypropionic acid and derivatives thereof, and a preparation method thereof. The catalyst includes a molded body in which primary particles of hydroxyapatite are aggregated, wherein a volume average particle size of the primary particles is 15 μm to 150 μm, and a P value represented by the following Equation 1 is 3.5 to 19: P = A * B / C [ Equation 1 ] wherein in Equation 1. A represents the volume average particle size (μm) value of powder, B represents a crush strength (N) value, and C represents a specific surface area (m2/g) value. The catalyst has very excellent life characteristics while exhibiting a high reaction yield and selectivity.
