Roger Cristóbal Gronerth Pinedo of Somos Perú leads the Maynas provincial mayoral market at 67.8% after securing a clear plurality in the October 4, 2026 election. With over 93% of ONPE tallies processed, he holds roughly 33.5% of valid votes—more than double the share of second-place Joel Ronal Parimango Álvarez of Alianza para el Progreso—while Sergio Antonio Donayre Ramírez, Boris Guido Morey Sifuentes, and Ernesto Concha La Torre trail further back. Earlier 2026 polling had shown a fragmented field with Morey or Gronerth trading the top spot, but Gronerth consolidated support in the final weeks through party organization and name recognition in the Iquitos metropolitan area. The remaining candidates each sit below 5% in the market, consistent with their lower vote shares and the absence of any late shifts in the partial count that could alter the outcome.
