The bombing of Toyokawa (豊川空襲, Toyokawa dai-kūshū) was part of the strategic bombing campaign waged by the United States of America against military and civilian targets and population centers during the Japan home islands campaign in the closing stages of the Pacific War in 1945.

The Tōkaidō Main Line railway connecting Tokyo with Osaka also ran through the city.

During this attack, 135 B-29 Superfortress bombers of the USAAF 20th Air Force, 58th 73rd, 313th, and 314th Bombardment Wings launched from Guam, Saipan and Tinian.

Victims included 452 schoolchildren and teenaged girls, some of whom had been conscripted and many of whom had volunteered to work at the Naval Arsenal.

Another B-29 lost course and dropped its bombs on the rural village of Futamata (now part of Hamamatsu, Shizuoka).
