ニューハンプシャー州議会代議院（英語:The New Hampshire House of Representatives）は、アメリカ合衆国ニューハンプシャー州の州議会であるニューハンプシャー州議会の下院にあたる。下院は州内の203の選挙区から選出された400人の議員で構成されており、各議員は州内の郡を分割して作られた選挙区から選出される。平均すると、各議員は約3,300人の住民を代表することになり、これは全米で最も人口に対する下院議員比率が低いことになる。

 概要 
州下院は、米国の州議会の中で圧倒的に最大規模である。2番目に大きいペンシルベニア州下院は203人の議員で構成されている。ニューハンプシャー州議会代議院は、英語圏では4番目に大きい下院議会である(アメリカ合衆国議会下院の435人、インドのローク・サバーの543人、英国の庶民院の650人に次ぐ)。

多くの州議会とは異なり、両党の議員が5つのセクションに分かれて座っているため、単に「通路」を渡るというわけではない。議員の自動車のナンバープレートには座席のセクションと番号が記載されており、議員が個人的に自動車にプレートを貼る場合は、その費用を議員が負担する。議長や政党のリーダーのプレートには役職が記載される。座席はあらかじめ割り当てられているため、その場所に座らなければならない。議員の個人的な希望は聞かれるが、通常、委員長や特別なニーズのある議員には、優先的に通路側の席が割り当てられる。6番目のセクションは、議場前方の議長の席である。

州下院は、1819年以来、ニューハンプシャー州会議事堂の下院会議場で会合を開いている。下院会議場は、現在も立法機関として使用されている米国最古の議場である。大きなアーチ型の窓が壁に沿って並んでいる。演壇には、ジョン・パーカー・ヘイル、エイブラハム・リンカーン、ジョージ・ワシントン、フランクリン・ピアース、ダニエル・ウェブスターの肖像画が掲げられている。

 選挙制度 
選挙区は人口に応じて議席数が異なり、最も人口の少ない選挙区では1人、最も人口の多い選挙区では10人(比例代表区の議席は含まない)の議員を選出する(ロッキンガム選挙区第13区には10人の議員がいる)。有権者は、その選挙区で補充される議席数と同じ数の票を投じることができる。例えば、定数2名の選挙区では有権者は最大2人の候補者に投票でき、定数10名の選挙区では最大10人の候補者に投票できる。 完全連記制では、ある政党が選挙区内の全議席を独占することがよくある。単純小選挙区制で選出された選挙区と同様に、政党代表の比例性は一般的に生み出されない。人口をより均等に配分するために、複数の地区(浮動地区を含む)にまたがる自治体もある。

 委員会 
現在の州下院の委員会の指導部は以下の通りである。

委員長は委員会の議長であり、公聴会の進行、秩序の維持、委員会規則の施行を担当する。委員長が不在の場合は、副委員長が公聴会の議長を務める。書記は委員会の出席、議事録、投票記録など、すべての事務管理を担当する。少数党筆頭議員は委員会における少数党の代表であり、伝統的に多数派が交代した際に委員長に任命される。委員長と副委員長は議長の任命によりその職に就き、議長の意向に沿って職務を遂行する。一方、筆頭委員は少数党院内総務の推薦に基づき議長が任命する。事務官は委員長が選任する。議長は、委員、委員長、副委員長、委員長秘書について、一方的に解任または配置転換を行うことができる。
