Kita-Saitama District (北埼玉郡, Kita-Saitama-gun) was a district located in Saitama Prefecture, Japan.

Prior to its abolition, Kita-Saitama District had three towns:

• Town of Kisai (騎西町; Kisai-machi)
• Town of Kitakawabe (北川辺町; Kitakawabe-machi)
• Town of Ōtone (大利根町; Ōtone-machi)

On March 23, 2010, all three towns merged with the city of Kazo to newly create the city of Kazo and the district dissolved. As a result, it was the first district to dissolve within Saitama Prefecture since the districts were reorganized in 1896.
