This is a complete list of Acts of the Parliament of Great Britain for the year 1798. For acts passed up until 1707 see List of Acts of the Parliament of England and List of Acts of the Parliament of Scotland. See also the List of Acts of the Parliament of Ireland to 1700 and the List of Acts of the Parliament of Ireland, 1701–1800.
For Acts passed from 1801 onwards see List of Acts of the Parliament of the United Kingdom. For acts of the devolved parliaments and assemblies in the United Kingdom, see the List of Acts of the Scottish Parliament, the List of Acts of the Northern Ireland Assembly, and the List of Acts and Measures of Senedd Cymru; see also the List of Acts of the Parliament of Northern Ireland.
The number shown after each Act's title is its chapter number. Acts are cited using this number, preceded by the year(s) of the reign during which the relevant parliamentary session was held; thus the Union with Ireland Act 1800 is cited as "39 & 40 Geo. 3. c. 67", meaning the 67th act passed during the session that started in the 39th year of the reign of George III and which finished in the 40th year of that reign. Note that the modern convention is to use Arabic numerals in citations (thus "41 Geo. 3" rather than "41 Geo. III"). Acts of the last session of the Parliament of Great Britain and the first session of the Parliament of the United Kingdom are both cited as "41 Geo. 3".
Acts passed by the Parliament of Great Britain did not have a short title; however, some of these Acts have subsequently been given a short title by Acts of the Parliament of the United Kingdom (such as the Short Titles Act 1896).
From the session 38 Geo. 3 onwards, "public acts" were separated into "public general acts" and "public local and personal acts".
