言語系統	ニジェール・コンゴ語族?
下位言語	イジョ諸語; ?デファカ語;

イジョイド語群（Ijoid languages）は、イジョ語（Ịjọ）とデファカ語を結び付ける、提案中（未実証）言語のグループである。ただし、類似点は、イジョ語がデファカ語に影響を与えたことが原因である可能性がある^[2]。

イジョイド語群はニジェール・コンゴ語族の分派を形成し、基本語順は主語-目的語-動詞である。これはニジェール・コンゴ語では珍しく、マンデ諸語とドゴン諸語とのみ共有する特徴である。マンデ諸語やドゴン諸語と同様に、イジョイド諸語にはニジェール・コンゴ語族の特徴と考えられる名詞クラスシステムの痕跡すら欠如しているため、ニジェール・コンゴ語から早期に分裂した可能性がある。言語学者のGerritDimmendaalは、ニジェール・コンゴ語族に含まれていることに完全に疑念を抱いており、イジョ語/イジョイド語は独立した語族であると考えている^[3]^[4]。
