Dysprosium titanate (Dy2Ti2O7) is an inorganic compound, a ceramic of the titanate family, with pyrochlore structure. Its CAS number is 68993-46-4.

Dysprosium titanate, like holmium titanate and holmium stannate, is a spin ice material. In 2009, quasiparticles resembling magnetic monopoles were observed at low temperature and high magnetic field.[1][2]

Dysprosium titanate (Dy2TiO5) is being investigated as a new material for nuclear reactor control rods.[citation needed]
