We present the results of our search for WR stars in three of M33's most massive giant HII regions, namely NGC 604, NGC 595 and NGC 592. A few of the putative “superluminous” WR stars are shown to be crowded multiple systems. We also compare the WR populations of the most massive GHRs in the Local Group. WN stars are 5 times more numerous on the average than WC stars in these large complexes. The variations among GHR WR populations are discussed in the context of metallicity and age differences.
