Muireachan is Irish (Gaelic) in Origin.

Muireachan is a Gaelic diminutive formed with -án/-an from Muireach/Muireadhach, names documented across medieval Ireland and the Scottish Highlands. The root likely connects to Old Irish muir “sea” with the adjectival -each, yielding a sense of “seafaring, maritime,” later glossed as “seaman” and sometimes “lord/master.” Bearers include ecclesiastical and poetic figures such as Muireadhach Ua Dubhthaigh and Muireadhach Albanach, reflecting the name’s learned and noble associations.

Variants span Muireach (Scottish Gaelic), Muireadhach (Irish), and diminutives Muireadhán/Muiredán alongside Muireachan. Anglicisations include Murdoch/Murdock (often via Muireach) and occasionally Murray from Muireadhach; note that Murchadh - source of some Murdoch lines - is a distinct “sea-battle” name. As a given name today, Muireachan reads as “little Muireach,” evoking an affectionate “little mariner” or “young lord.”
