The Varangian Runestones are runestones in Scandinavia, primarily in Sweden, that mention voyages to the East (Old Norse: Austr) or the Eastern route (Old Norse: Austrvegr), or to more specific eastern locations such as Garðaríki in Eastern Europe.

There are also many additional runestones in Scandinavia that talk of eastward voyages such as the Greece Runestones, Italy Runestones, and inscriptions left by the Varangian Guard. Other runestones that deal with Varangian expeditions include the Serkland Runestones (dealing with expeditions to the Middle East) and the Ingvar Runestones (erected in honor or memory of those who travelled to the Caspian Sea with Ingvar the Far-Travelled). There is also a separate article for the Baltic expeditions runestones. In addition, there were also voyages to Western Europe mentioned on runestones that are treated in the articles Viking Runestones, England Runestones and Hakon Jarl Runestones.

Most of the runestones were raised during the Christianization of the 11th century when the making of runestones was fashionable, but notably, the Kälvesten Runestone Ög 8 was made in the 9th century when the Varangians played a central role in what would become Russia and Ukraine. This vast area was a rich source of pelts, hides and people, and it was an important component in the contemporary Swedish economy. Its Old Norse name meant 'land of fortresses' and was derived from the chains of fortresses that had been constructed along the trade routes.

All of the stones were engraved in Old Norse with the Younger Futhark and the message of many of the inscriptions can be summarized with a poem in the fornyrðislag style found on the Turinge Runestone Sö 338:

Brøðr vaʀu
þæiʀ bæzstra manna,
a landi
ok i liði uti,
heldu sina
huskarla ve[l].
Hann fioll i orrustu
austr i Garðum,
liðs forungi,
landmanna bæzstr.

These brothers were
the best of men
in the land
and abroad in the retinue,
held their housecarls well.

He fell in battle
in the east in Garðar (Russia),
commander of the retinue,
the best of landholders.

Below follows a presentation of the runestones based on the Rundata project. The transcriptions into Old Norse are mostly in the Swedish and Danish dialect to facilitate comparison with the inscriptions, while the English translation provided by Rundata gives the names in the de facto standard dialect (the Icelandic and Norwegian dialect):

This runestone in style Pr3 is one of the runestones in Hagby. It was discovered in 1930 in the basement under the main building of the old estate Lissby which had been demolished in the late 19th century. It had been inserted in the basement wall with the engraved side visible together with the runestones U 152 and U 154. When the basement collapsed, the runestone was splintered into a great number of minor and major pieces of which the top part was the largest one. A fragment of the stone was discovered in the field on the property of Lissby. All in all, no less than 70 pieces were reassembled, and in 1931, the repaired stone was raised in the garden of Hagby. The stone is in granite and it is 2.60 m tall and 1.5 m wide. The inscription is damaged and especially in its beginning and end. It refers to several stones and one of them was probably the runestone U 155.
