+#### fs.lchown(path, uid, gid, callback)<a name="lchown"></a>
+
+lchown() is like chown(), but does not dereference symbolic links. Asynchronous [lchown(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chown.html). Callback gets no additional arguments. Both `uid` (user id) and `gid` (group id) arguments should be a JavaScript Number.  By default, `0x0` is used (i.e., `root:root` ownership).
+
+Example:
+
+```javascript
+fs.lchown('/myfile.txt', 500, 500, function(err) {
+  if(err) throw err;
+  // /myfile.txt is now owned by user with id 500, group 500
+});
+```  
+
 #### fs.chmod(path, mode, callback)<a name="chmod"></a>
 
 Changes the mode of a file. Asynchronous [chmod(2)](http://pubs.opengroup.org/onlinepubs/009695399/functions/chmod.html). Callback gets no additional arguments. The `mode` argument should be a JavaScript Number, which combines file type and permission information.  Here are a list of common values useful for setting the `mode`:
