Lead(II) titanate is an inorganic compound with the chemical formula PbTiO₃. It is the lead salt of titanic acid. Lead(II) titanate is a yellow powder that is insoluble in water.

At high temperatures, lead titanate adopts a cubic perovskite structure. At 760 K, the material undergoes a second order phase transition to a tetragonal perovskite structure which exhibits ferroelectricity. Lead titanate is one of the end members of the lead zirconate titanate (Pb[Zr_xT_1−x]O₃, 0 ≤ x ≤ 1, PZT) system, which is technologically one of the most important ferroelectric and piezoelectric ceramics; PbTiO₃ has a high ratio of k33 to kp with a high kt.

Lead titanate occurs in nature as mineral macedonite.
