Douglas B-18 Bolo (kanadska oznaka Douglas Digby) je bil srednji bombnik, ki so ga uporabljale ameriške USAAC in kanadska RCAF od poznih 1930ih do zgodnjih 1940ih. Proizvajalo ga je podjetje Douglas Aircraft Company, skupaj so zgradili 350 letal. Zasnovan je bil na podlagi DC-2. B-18 naj bi nasledil Martina B-10.

B-18 je bil na začetku 2. svetovne vojne že precej zastarel, imel je sorazmerno majhno hitrost, majhen bombni tovor in je imel slabo samoobrambno oborožitev. Zato so ga kasneje uporabljali kot protipodmorniško letalo in za transport lahkih tovorov.
