9905 Tiziano is a main belt asteroid. It orbits the Sun once every 3.73 years.
Discovered on September 24, 1960 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates made by Tom Gehrels at the Palomar Observatory with the Samuel Oschin telescope, it was given the provisional designation "4611 P-L". It was later renamed "Tiziano" after Renaissance painter Tiziano Vecellio.
