Alastair McNaughton Smallwood known as Alastair Smallwood (18 November 1892 – 12 June 1985) was a rugby union wing who played 64 games for Leicester Tigers and 14 games for England between 1920 and 1925. Smallwood was born in Scotland but educated at Newcastle Royal Grammar School and went to Gonville and Caius College, Cambridge on an organ scholarship. He played in the 1919 Varsity Match and scored a drop goal as Cambridge beat Oxford 7-5. This led to Smallwood making his England debut on 31 January 1920 against France in the 1920 Five Nations Championship.
