Niall Armstrong (born 8 October 1999) is an Irish rugby union player who plays at scrum half for Exeter Chiefs.
From Ulster, he attended Royal Belfast Academical Institution.[4] He also attended Exeter University where he captained the first-XI rugby union team.[5]
He made his debut for Exeter Chiefs in September 2024.[5] During his first season for Exeter, he was mainly used as a replacement at the start of the season but scored two tries for the club in the opening weeks of the season.[6] In November 2023, he was given a red card in the Rugby Premiership for a high boot striking Northampton Saints fly half Fin Smith in the face which was deemed as reckless.[7] It was an action that his Exeter head coach Rob Baxter described as "not deliberate" and Smith described as just "one of those things".[8] [9] In April 2024 after making eleven appearances for the Chiefs he agreed a contract extension.[5]
