The inadequate oxygen supply in solid tumor causes hypoxia, which leads to drug resistance and poor chemotherapy outcomes. To solve this problem, a cancer cell membrane camouflaged nanocarrier is developed with a polymeric core encapsulating hemoglobin (Hb) and doxorubicin (DOX) for efficient chemotherapy. The designed nanoparticles (DHCNPs) retain the cancer cell adhesion molecules on the surface of nanoparticles for homologous targeting and possess the oxygen‐carrying capacity of Hb for O 2 ‐interfered chemotherapy. The results show that DHCNPs not only achieve higher tumor specificity and lower toxicity by homologous targeting but also significantly reduce the exocytosis of DOX via suppressing the expressions of hypoxia‐inducible factor‐1α, multidrug resistance gene 1, and P‐glycoprotein, thus resulting in safe and high‐efficient chemotherapy. This work presents a new paradigm for targeted oxygen interference therapy by conquering hypoxia‐involved therapeutic resistance and achieves effective treatment of solid tumors.
