Kilmacud (Irish: Cill Mhic Oda, meaning "The Church of the Son Of Oda") is a suburban area in Dublin in Dún Laoghaire–Rathdown.
Kilmacud is north of Sandyford, east of Dundrum and south of Goatstown. The west end of the Lower Kilmacud Road starts in Goatstown, heading in a southerly direction. It then goes southeast through what appears to be a narrow shortcut and on out to the end of Drummartin Road and turns east. From there it continues eastwards through to the Stillorgan dual carriageway or N11. In total, it is about 2.6 kilometres or 1.6 miles long. The Upper Kilmacud Road starts in Dundrum and going uphill initially it continues eastward, levels off, and continues until a sharp corner brings it northward and downhill. It joins the Lower Kilmacud Road close to St. Laurence's Boys School. It is about 2.9 kilometres or 1.8 miles long.
The difference between Kilmacud and Stillorgan is somewhat ambiguous. For example, Kilmacud Crokes GAA club is located in Stillorgan and Stillorgan's Roman Catholic parish is called Kilmacud. Kilmacud can be described as the area between and immediately around the Upper and Lower Kilmacud Roads. A now gone placename sign for Stillorgan stood up until the 1970s near Beaufield Park, which is on the section of the Lower Kilmacud Road running between the shops near St. Laurence's Church, and the Stillorgan Shopping Centre. This would have been on the western edge of the Stillorgan, and many of the existing housing estates mentioned earlier would not have been in place prior to the 1950s, so it would have marked the beginnings of a built-up area. The area now referred to as Kilmacud would have been on the western side of the sign, with the Chapel of SS Laurence and Cuthbert close by. This was long before the current church dedicated just to St. Laurence O'Toole, which opened in 1969.
