A marker pen, marking pen, or marker, is a pen which has its own ink-source, and usually a tip made of a porous material, such as felt or nylon.
Markers are available in a variety of sizes.
- Fine-tip markers, typically used for writing on paper.
- Medium-tip markers, typically used by children for coloring.
- Large-tip markers, typically used for writing on non-paper surfaces.
- Wide-tip markers, typically used for highlighting text that is already present on paper. (This device is usually called a highlighter.)
A non-permanent marker
uses an erasable ink — an ink that adheres to the writing surface without binding or being absorbed by it — for temporary writing with overhead projectors
, and the like. They may also be used by children when adults want to be able to clean up after them. The erasable ink does not contain the toxic chemical compounds xylene
, unlike permanent markers.
" markers, with fluorescent
but otherwise invisible inks, are used for marking valuables in case of burglary
. The owner of a stolen, but recovered item can be determined by using ultraviolet light

Marker pens with election ink
(an indelible dye and often a photosensitive
agent such as silver nitrate
) used to mark the finger, and especially cuticle of voters in elections in order to prevent electoral fraud
such as double voting. The stain stays visible for a week or two and may also be used to assist in vaccinations in developing world communities and refugee camps.
, from Richmond Hill, New York, is credited with inventing the marker in 1952.
. He placed a felt tip on the end of a small, stout bottle of permanent ink and discovered that the resulting marks saturated a heavy, absorbent surface, yielding rich color and permanence.
The felt tip pen played a major role in the Apollo 11 mission. Neil Armstrong accidentally broke a circut breaker switch that was essential to starting the Lunar Lander's engines for lift off from the moon. The pen was used to activate the switch, thus starting the engine and saving the Astronauts' lives.
The use of the terms "marker" and "felt-tipped pen" varies significantly among different parts of the world. This is because most English dialects contain words for particular types of marker, often generic
brand names, but there are no such terms in widespread international use.
