Wuding County (Chinese: 武定县; pinyin: Wǔdìng Xiàn; Chuxiong Yi script: , IPA: /lo33 di33 bu33/) is under the administration of the Chuxiong Yi Autonomous Prefecture, in the north-central part of Yunnan province, China, bordering Sichuan province to the north.

[2] Wuding was historically more important, being the center of a Zhou, equivalent to a prefecture-level division.

[3] The Wuding County Gazetteer (1990) lists the following Yi subgroups.

According to the Chuxiong Prefecture Gazetteer (1993:411), the Luomian 罗缅, a Hani subgroup, are located in Nigagu 尼嘎古.

Gao (2017) classifies Geipo of Wuding County as closely related to Miqie, and is not the same as the Northern Loloish language Gepo.
