Tattoo ink is pigment suspended in a carrier, and the carrier is where an animal ingredient is most likely to hide. Glycerine can come from an animal or a plant, and most brands don't say which on the bottle.

Vegan optionInk explicitly labelled vegan, or a vegan-only studio
VerdictSometimes
Where it hides
The carrier solution (glycerine), rarely disclosed as animal or plant
Older or artisan black ink using bone char pigment
Unlabelled ink at a studio that hasn't asked its supplier
Ink explicitly labelled vegan, from a small but growing set of brands
Pigment and carrier are two separate questions
A tattoo needle doesn't inject a single substance. It injects a pigment suspended in a liquid carrier, and each has its own supply chain, as a recent peer-reviewed review of tattoo ink safety lays out.
Primary source 01 / 02
Tattoo inks typically comprise pigments and various additives like carriers, solvents, preservatives, and stabilizers.
The pigment side is the easier half to settle. Modern black is almost always carbon black rather than the older animal-derived option: bone char, made by charring animal bone, was a genuine historical ink pigment, and a version of it is still manufactured today for a handful of specialist markets, but it lost most of its ground to cheap petroleum-derived carbon black by the mid-20th century. The carrier is the half worth asking about.

Carriers, such as glycerin or water‐based solutions, aid in ink application
Glycerine can be rendered from animal fat or pressed from a plant oil, and either version works the same way in a bottle of ink. Manufacturers rarely print which one they used, so a plain ingredient scan won't settle it. The clearest signal is a brand or studio that states its ink is vegan outright, which by definition rules out animal glycerine along with any animal-derived pigment. Without that claim, the honest position is that the bottle alone won't tell you.
CondomsMost latex condoms are made using casein, a milk protein, to smooth and stabilise the rubber during manufacturing. A small number of brands leave it out and label themselves vegan.

Frequently asked
Is black tattoo ink made from animal bone?
Rarely today. Bone char, a pigment made by charring animal bone, was a real historical ink ingredient and a version of it is still produced for niche markets, but it was mostly replaced by carbon black, a petroleum byproduct, by the mid-20th century.
What part of tattoo ink is most likely to be animal-derived?
The carrier rather than the pigment. Glycerine, one of the most common carriers, can be made from animal fat or plant oil, and ink makers don't generally specify which on the label.
How do I get a vegan tattoo?
Ask the studio directly, or look for a brand that states its ink is vegan. A growing number do, and some tattoo studios now stock only vegan ink as standard.
