Il biossido di titanio (o ossido di titanio(IV) o diossido di titanio) o E171, nella codifica europea degli additivi alimentari, noto anche come titania, è un composto chimico che si presenta sotto forma di polvere cristallina incolore, tendente al bianco; ha formula chimica TiO2. Il TiO2 in natura è presente in cinque forme cristalline diverse: il rutilo, l'anatasio, la brookite e i due polimorfi di altissima pressione (per impatto da meteoriti) akaogiite e TiO2 II, che possono essere colorate a causa di impurità presenti nel cristallo. Il rutilo è la forma più comune: ciascun atomo di titanio è circondato ottaedricamente da sei atomi di ossigeno; l'anatasio ha struttura tetragonale, più allungata rispetto a quella del rutilo, mentre la brookite ha struttura ortorombica.
