ノーベル賞受賞者数国別ランキング（2025年10月現在）

2025年10月6日現在、ノーベル賞の発表は生理学・医学賞のみ完了しており、他の分野（物理学、化学、文学、平和、経済学）はまだ発表されていません。したがって、累積ランキングは2024年までの全受賞者プラス2025年の生理学・医学賞受賞者（米国2人、日本1人）を含みます。総受賞者は約1,015人（個人・団体）で、国別カウントは受賞者の出生地や所属に基づき、重複カウントされる場合があります。以下はトップ10国のランキングで、総数と分野別の内訳を示します。データはウィキペディアと公式ソースに基づいています。

• 注: 2025年の追加: 生理学・医学賞でMary E. Brunkow（米国）、Fred Ramsdell（米国）、Shimon Sakaguchi（日本）が受賞。これにより米国の総数が423に、日本が30に更新。

日本人受賞者について

日本は2025年現在、ノーベル賞受賞者30人（個人・団体を含む、ディアスポラ含む）を輩出しており、主に科学分野で強みを発揮しています。以下は全受賞者のリストで、年、分野、名前、受賞理由を記載。カウントには日本国籍者や出身者を含み、メディアでは29-31人とされることがあります（例: Ishiguroは英国籍取得後）。2025年にSakaguchiが追加され、生理学・医学分野で6人目となりました。
