William End, QC (1798 – December 14, 1872) was an Irish-born lawyer and politician in New Brunswick.
End was born in Limerick and came to New Brunswick, where he studied law with William Botsford.
End set up practice at Saint John as an attorney, was called to the bar in 1825 and moved to Newcastle.
End became the first clerk for Gloucester County after Confederation and later served as a stipendiary magistrate.
End died in a fire in his office at Bathurst, likely assassinated by a man whom he had sentenced to time in jail.
