The street is named after the church of St. Thomas, founded in 1175 near St. Catherine's church. The founder was William FitzAldelm, deputy and kinsman of King Henry II. The church was dedicated to Thomas Beckett (St. Thomas the Martyr), who had recently been murdered in his cathedral at Canterbury by followers of the king. The church became a rich and powerful monastery, which controlled the Liberty of Thomas Court and Donore. In 1539 it was dissolved with all the monasteries by Henry VIII. Over the following 150 years the churches in the neighbourhood passed over to the reformed church, while Roman Catholic priests led a precarious existence tending to the larger part of the population, which remained faithful to the old religion.
In 1803 this street was the scene of the events surrounding the insurrection organised by Robert Emmet, where Lord Kilwarden was killed. Many of the participants in what turned out to be a riot were from this street and neighbouring streets.
The National College of Art and Design is located on Thomas Street, as is John's Lane Church, which has the highest steeple in the city, Vicar Street (music venue), Michelin-starred restaurant Variety Jones, St. Catherine's church where the patriot Robert Emmet was executed, as well as The Thomas House bar and venue.

In 1907, it was planned to build a fire station on Thomas Street, to replace the makeshift station already at Winetavern Street, a proposal that had been on the table since 1898. In 1909, some city councillors moved to shelve the plans, proposing that the money be spent on paying off the Dublin Corporation's loans instead. However this motion failed to garner enough votes to pass, after a lengthy debate, and in November 1909 building of the station was finally given the go-ahead. The building was renovated in 2008 and became part of the National College of Art and Design.
