'''Titanium(III) phosphide''' (TiP) is an inorganic chemical compound of [[titanium]] and [[phosphorus]]. Normally encountered as a grey powder,<ref name = "Perry" /> it is  a metallic conductor with a high melting point.<ref name = "Schnering">H.G. Von Schnering, W. Hönle  ''Phosphides - Solid state chemistry''  Encyclopedia of Inorganic Chemistry Ed. R. Bruce King (1994) John Wiley & Sons {{ISBN|0-471-93620-0}}</ref>  It is not attacked by common acids  or water.<ref name = "Perry" /> Its physical properties stand in contrast to the group 1 and group 2 phosphides that contain the P<sup>3<nowiki>&minus;</nowiki></sup> anion (such as [[sodium phosphide|Na<sub>3</sub>P]]), which are not metallic and are readily hydrolysed.<ref name = "Schnering" /> Titanium phosphide is classified as a "metal-rich phosphide", where extra valence electrons from the metal are delocalised.<ref name = "Schnering" />

Titanium phosphide can be prepared by the reaction of TiCl<sub>4</sub> and PH<sub>3</sub>.<ref name = "Perry" />

Titanium phosphide should not be confused with [[titanium phosphate]] or titanium isopropoxide, both of which are sometimes known by the acronym TIP.
