A khelrtva (Georgian: ხელრთვა, pronounced [χeɫɾtʰʷa]) is a Georgian calligraphic signature, monogram or seal, originally used by the Georgian monarchs, queens consort, patriarchs, royalty and nobility, universally used since the early eleventh century.

The word khelrtva literally means 'to decorate, adorn or beautify with hand' in Georgian, kheli (ხელი) meaning a hand and rtva (რთვა) meaning to decorate or adorn.

Khelrtva signatures were written in one of the three Georgian scripts, mostly in Nuskhuri and Mkhedruli scripts, though the monograms especially the royal ones were written in Asomtavruli script. Every Georgian monarch had their own individual khelrtva and was known as საუფლოჲ ხელი (sauploy kheli) literally meaning 'Hand of the Lord'. The tradition of khelrtvas is still in use in Georgia.
