The FIBA EuroBasket 2005 Division B was the first EuroBasket Division B tournament, the lower tier of the EuroBasket Tournament. At the same time that Division A had the European Championship, division B had a championship to determine which teams would get promoted into division A for the following year.
The fifteen teams were allocated in four groups. The winners of each group played a two-legged tie. The winners of each heat qualified for the EuroBasket 2007 qualification.
