Saint Clement of Ohrid was one of the most prolific and important writers in Old Church Slavonic.
He is credited with the Panonic Hagiography of Saint Cyril and Saint Methodius.
Clement also translated the Flower Triode containing church songs sung from Easter to Pentecost and is believed to be the author of the Holy Service and the Life of St. Clement of Rome, as well as of the oldest service dedicated to St. Cyril and St. Methodius.
The invention of the Cyrillic alphabet is also usually ascribed to him although the alphabet is most likely to have been developed at the Preslav Literary School at the beginning of the 10th century (see Cyrillic script).

Medieval frescoes of Saint Clement exist throughout the modern-day territories of North Macedonia, Serbia and northern Greece, with the vast majority being located in North Macedonia.

The first modern Bulgarian university, Sofia University, was named after Clement upon its foundation in 1888.
The Macedonian National and University Library, founded on November 23, 1944, also bears his name.
The University in Bitola, established in 1979, is named after Clement, as well as the Bulgarian scientific base, St. Kliment Ohridski on Livingston Island in the South Shetland Islands of Antarctica.

In November 2008, the Macedonian Orthodox Church donated part of Clement's relics to the Bulgarian Orthodox Church as a sign of good will.

In May 2018 was announced that in the ruins of a Ravna Monastery, near the village of Ravna in Provadiya Municipality, the signature of Saint Clement was identified on a stone plate with a large amount of graffiti on it.
The signature is dated as of April 24, 889.
The finding gives reason to assume that the disciples of Saints Cyril and Methodius were settled there at one stage, after being expelled from the Great Moravia and their reception in Bulgaria.
