==History== The name ''Ban Chaiyo'' dates back to when King Naresuan the Great and his brother, who later became King Ekathotsarot, defeated the King of Lan Na and Burmese soldiers in this area. The soldiers of Ayutthaya shouted ''Chaiyo'' (ไชโย, "hurrah") to celebrate.<ref name = angthong>{{cite web|url=http://kids-d.swu.ac.th/dspace/bitstream/123456789/1371/11/scan9.pdf|title=ไชโย ท้องที่ที่สมเด็จพระนเรศวรมหาราชชนะศึกพม่า|first=หวน|last=พินธุพันธ์}}</ref> It is unclear whether the name ''Chaiyo'' was given to the area (as ''Ban Chaiyo''; Chaiyo village) or the prominent Buddhist temple {{ill|Wat Chaiyo Worawihan|th|วัดไชโยวรวิหาร|lt=Wat Chaiyo}} first, and which was subsequently named after which.<ref name = angthong />

In the past, Chaiyo was called Ban Makham. When it was officially promoted to a district, the government selected the name "Chaiyo" because of its storied past.<ref name = angthong />

==Geography== Neighbouring districts are (from the north clockwise): Phrom Buri of Sing Buri province, Tha Wung, and Mueang Lopburi of Lopburi province; Ban Phraek and Maha Rat of Ayutthaya province; and Mueang Ang Thong and Pho Thong of Ang Thong Province.

==Administration== The district is divided into nine sub-districts (''tambons''), which are further subdivided into 56 villages (''mubans''). There are two townships (''thesaban tambons'') in the district. Chorakhe Rong covers ''tambons'' Chorakhe Rong, Chaiyaphum, Lak Fa, Chawai, Tri Narong, and parts of Chaiyarit. ''Tambon'' Chaiyo is completely covered by the township Ket Chaiyo.<!--เกษไชโย-->.
