A fingerpost (or guidepost) is a type of sign post consisting of a post with one or more arms, known as fingers, pointing in the direction of travel to places named on the fingers, often including distance information.

Fingerposts are a traditional type of sign used in the United Kingdom. The posts have traditionally been made from cast iron or wood, with poles painted in black, white or grey and fingers with black letters on a white background, often including distance information in miles.

In most cases, they are used to give guidance for road users, but examples also exist on the canal network, for instance. They are also used to mark the beginning of a footpath, bridleway, or similar public path.

In 1697 the Highways Act entered force in England, enabling magistrates to order the erection of "a stone or post with an inscription" at the "Place where Two or more Crosse High-ways meet". However, the oldest fingerpost still extant is thought to be that close to Chipping Campden in Gloucestershire, dated 1669 and pointing to Oxford, Warwick, Gloucester and Worcester (abbreviated to 'Gloster' and 'Woster'). The Highways Act 1766 and Turnpike Roads Act 1773 made use of fingerposts on turnpike roads compulsory.

The Motor Car Act 1903 passed road sign responsibilities to the relevant highway authority within the then United Kingdom of Great Britain and Ireland, although no specifications were set. Guidance was given in a 1921 circular that road direction signs should have 2+1⁄2-or-3-inch-high (64 or 76 mm) upper case lettering on a white background and white supporting poles. It also recommended that the name of the highway authority be included somewhere in the design.

Mandatory standards (The Traffic Signs (Size, Colour and Type) Provisional Regulations) were passed for Great Britain in 1933 which required poles to painted with black and white bands and lettering to be of a different typeface. Signposts were removed across much of the United Kingdom of Great Britain and Northern Ireland during World War II, lest enemy forces use them for navigation, and replaced in the late 1940s.

Road signing was next comprehensively reviewed in the United Kingdom from 1961 by the government-appointed Worboys Committee and the 1964 Traffic Signs Regulations brought in the signing system largely remaining in force today. Whilst the 1964 regulations did encourage local authorities to remove and replace traditional fingerposts with the new designs, it was not made compulsory to do so. Regulations did not, however, permit new fingerpost style signs to be erected until a design was permitted by the Department for the Environment in 1994 (in the Traffic Signs Regulations and General Directions of that year). Of note was that the design did not allow for mileages of over three miles to be expressed with the use of halves and quarters. It is thus that new fingerposts have been required to round the previously more precise distance measurements.^{[citation needed]}

Whilst the 1964 regulations did not bring about a general requirement to remove all fingerposts in Great Britain (signage in Northern Ireland being treated somewhat separately), some counties appear to have been more zealous than others in eradicating them. Fingerpost survival is highest in rural areas and away from major roads. Reacting to concern about the loss of historic fingerposts from the rural landscape, an advisory leaflet was issued by the Department for Transport and English Heritage in June 2005 which stated that "All surviving traditional fingerpost direction signs should be retained in-situ and maintained on a regular basis. They should be repainted every five years in traditional black and white livery. Other colours should be used only when these are known to have been in use before 1940". In recent years several county councils have embarked on restoration and repair programmes for their fingerpost stock, including the Highway Heritage Project in the Quantock Hills of Somerset.
