Dinucleon decay is a process that violates baryon number by two units. We present the first search for dinucleon decay to pions in a large water-Cherenkov detector. The modes O16(pp)→C14π+π+, O16(pn)→N14π+π0, and O16(nn)→O14π0π0 are investigated. No significant excess in the Super-Kamiokande data has been found, so a lower limit on the lifetime of the process per oxygen nucleus is determined. These limits are τpp→π+π+>7.22×1031 years, τpn→π+π0>1.70×1032 years, and τnn→π0π0>4.04×1032 years. The lower limits on each mode are about 2 orders of magnitude better than previous limits from searches for dinucleon decay in ironWe gratefully acknowledge the cooperation of the Kamioka Mining and Smelting Company. The Super- Kamiokande experiment has been built and operated from funding by the Japanese Ministry of Education, Culture, Sports, Science and Technology, the United States Department of Energy, and the U.S. National Science Foundation.
